Bug 255863

Application: yakuake (2.9.7)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.7-0.5-default x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- Custom settings of the application:
While in yakuake, open the konsole context menu, Configure Scrollback -> Unlimited scrollback and Save to current profile. Click OK. Close / exit / ctrl-d all tabs in yakuake -> Segmentation fault.

- Workaround:
You cannot change Scrollback back  to a limited 1000 lines from within yakuake. The setting is not saved since yakuake crashes on exit. You'll have to close yakuake, open konsole, open the context menu there and Configure Scrollback. Restart yakuake. While Scrollback is limited, yakuake stops crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
