Bug 278153

Application: choqok (1.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I just started the application. After the copmuter boots and I login to my KDE account I manually start KMail, Pidgin or Kopete and then Choqok. I'm wandering if the problem is related to the KDE wallet (see below).

- Unusual behavior I noticed:
There was a message from Choqok telling me that "the opration requires authentication". It is weird because i didn't do anything. It seems to be some kind of automatic timeline refresh request.

- Custom settings of the application:
I've changed the interval to refresh to 5 minutes. It is also only connecting to twitter.com and not to other services. I'm behind a proxy (MS ISA server). Another thing to notice is that at home (where I only have a NAT router) I often get the crash on start-up. I'm suspecting, though I have no evidence or proof, that it might be caused by Choqok trying to access the KDE wallet and reaching some kind of racing condition with other KDE components.

The crash can be reproduced every time.

-- Backtrace:
