Bug 270926

Application: choqok (1.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu Natty (development branch)

-- Information about the crash:
Noticed since yesterday, after applying latest Kubuntu 11.04 beta updates (and restarting)

- What I was doing when the application crashed:

On starting up Choqok, it opens its window, loads a bunch of new tweets, then crashes. When reopening it most of the times (not always) looks like the last tweets had not been previously loaded, then it loads them again, then crashes again.

Opening a new bug as there's something new here : Chokoq has always crashed on open "from time to time", but now it's to the points that it's *all* the times and has become basically unusable (which makes me unhappy :-( )

The crash can be reproduced every time.

-- Backtrace:
Application: Choqok (choqok), signal: Segmentation fault
