Propane crashing my system, "network error"

When I boot up Propane it freezes up, along with the rest of my system, and afterwards displays a "network error" message. It used to work fine. This happened out of the blue. Any thoughts?

    Hi Robert,

    Sorry for the delay in replying to you, I'm in the UK on family business this week.

    The first thing to check is whether it's just propane that has the problem. Are you able to open campfire in (specifically) Safari?

    Also, are there messages in from Propane? If so, please paste them here.

    Finally, in case it's not obvious, can you think of anything that happened on your system around the time it started failing? Such as an upgrade, VPN changes or... dropping it on the floor (just did that myself).

    Regards, Trev

    Thanks for your (actually very quick) response.

    I can open Campfire in Safari, yes. These are messages from

    7/2/10 10:43:51 AM Propane[89975] CFPropertyListCreateFromXMLData(): Old-style plist parser: missing semicolon in dictionary.
    7/2/10 10:44:01 AM quicklookd[89973] [QL] 'Creating thumbnail' timed out for '' (Start date: 2010-07-02 10:43:41 +0200)

    Sometimes it loads (after freezing up the system), sometimes it just gives me the network error.

    I believe I updated the app before. Not sure when this started happening exactly though.

    Hi Robert,

    this is all very odd. Can you let me know the following:

    • Do you have a Propane license?
    • is the quicklookd "creating thumbnail" message in always present after starting Propane?
    • is that quicklookd message seen in other places in (not near Propane messages)?
    • you mention that it causes your whole system to 'freeze up' - do you genuinely mean frozen (mouse doesn't work, keyboard doesn't work) or are you able to use other already-running applications?
    • do you (or did you) have a VPN set up?

    Finally, can you please let me know what version of OSX, Safari and Propane you have installed?

    Sorry I don't have anything better than more questions at the moment, hopefully we can get to the bottom of this.

    Regards, Trev

    Hi Trevor,

    • I have a license, yes
    • My bad, it has nothing to do with Propane
    • I can use my mouse, but that's about it. Google Chrome or finder aren't usable for instance.
    • Sorry for forgetting this: no, don't have a VPN.
    • I'm using OSX 10.6.4, Safari 5.0 and Propane 1.0.8.

    Hope this helps! Thanks :)

    Hi Robert,

    Okay, you're using the same setup as me (OSX/Safari) so I'm trying to isolate what could possibly be causing the hang.

    First of all, I see you mentioned that Google Chrome is affected so I just wanted to double-check: when I asked if Campfire worked okay in Safari, I really did mean Safari specifically because they're quite closely intertwined.

    If you assumed I meant "in a web browser" and tested against Chrome then could you please recheck with Safari?

    After that, the only thing that Propane does, which Safari does not, is to check the Sparkle update feed for Propane. Does load in Safari for you?

    Another thing that might set Propane apart is if you're using Little Snitch or some other application firewall to block Propane's access. That sort of thing should have no system-wide impact but it'll be helpful to know if you're using something like Little Snitch...

    I'll be honest: I really think this is a symptom of a system problem rather than a bug in Propane. I have a hard time coming up with any scenario where Propane's opening of a URL connection could cause an entire machine to lock-up (assuming Safari works fine).

    I have seen reports of quicklookd timeouts (along with graphics-card complaints) being responsible for OSX hangs and beachballs so the fact that you included a quicklookd timeout log (even though it's, as you say, unrelated to Propane) has me wondering if you've got system problems.

    Is that quicklookd warning something that happens a lot in your logs?

    As I write out this (very long) grasping-at-straws list of things to try... if this started shortly after upgrading Propane, I wonder if somehow the automatic Sparkle update messed up... It may be an idea to delete Propane and download a fresh copy from just in case.

    And speaking of "just in case" - this sort of unexplained behaviour always makes me run the Disk Utility app to check for problems, in case the unexplained glitches are actually harbingers of disk-doom.

    I'm really sorry I don't have a decisive answer for you yet - nobody's ever reported anything like this before so I'm still trying to feel my way around the issue.

    Let me know how you make out.

    Regards, Trev

    Well, I guess it's probably my system then. Here's a few short answers:

    • Campfire works fine in every browser, even Safari.
    • The appcast URL loads fine in Safari, although it does take a few seconds to show up.
    • I'm not using any firewall app.
    • No other warnings with quicklookd show up since the one I've posted here.
    • I've redownloaded Propane but it doesn't help.

    I realize that I'm probably the only one out there, so don't worry. I'll figure something out. Maybe AppZapper could help, or Disk Utility.

    Love the app! Thanks for the help!
