[Bug 303505] [NEW] Apply in Preferences dialog in Kompare crash

[wsfulton]

Public bug reported:

Binary package hint: kompare

Run:
kompare dir1 dir2

Open the preferences dialog... Settings, Configure Kompare. Then press
the Apply button. The program just hangs and after a while seg faults.
It seems to be stuck in a loop, here is the gdb stack trace:
