[konsole] [Bug 375540] Seg fault on startup

[Christoph Feck]

https://bugs.kde.org/show_bug.cgi?id=375540

--- Comment #3 from Christoph Feck <cfeck at kde.org> ---
It looks like there are ambiguous keyboard shortcuts. KXmlGui opens a message
box, and the crash could be related to the nested event loop in
QDialog::exec().

Try resetting your Konsole configuration, if you customized shortcuts.

Backtrace from comment #2:
