Bug 304679

Application: yakuake (2.9.8)
KDE Platform Version: 4.9.00
Qt Version: 4.8.2
Operating System: Linux 3.5.0-2.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I was closing a tab using the keyboard shortcut, nothing fancy.
I installed a few GBs of debug symbols in order to help tracking this one, hoping it helps :)

The crash can be reproduced some of the time.

-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
