Not sure if that helps. There are some debug symbols missing.

New crash information added by DrKonqi

choqok (1.1) on KDE Platform 4.6.00 (4.6.0) using Qt 4.7.1

- What I was doing when the application crashed:

I have two twitter accounts, and all I do here is hit ctrl-Q (exit app).  Same thing is likely occurring whenever I log out of KDE.
