Application: plasma-windowed (0.1)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

* Started Microblogging plasma widget (in window)
* Entered login and password for Twitter in settings
* Pressed OK, it started to authenticate, Plasma crashed

Can't reproduce it again (maybe it stored some settings and doesn't crash with such settings).

Seems that Bug 306234 is not the same (stacktraces look different).

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma Widgets shell (plasma-windowed), signal: Segmentation fault
