Bug 339055

Since upgrading to Qt 5.4.0 alpha, Konsole crashes when closing it.
It doesn't matter whether I achieve this by Ctrl+D or just by closing the window.

Konsole (and all KF5 components) are up-to-date from git as of now.

The backtrace is rather short and I couldn't find a similar one amongst all other "Crash on closing" reports.

Application: konsole (konsole), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
