Bug 470757

Application: semantik (1.2.9)

Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 5.16.5-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
After using Semantik about an entire day (opening and closing without crashes) i've started to receive a recurring crash event from KDE Crash Handler.

Steps to see the error:
1 - open Semantik;
2 - close Semantik.

It doesn't matter if Semantik is closed by pressing <ALT + F4> or clicking in the close button (or using the exit inside File menu), it will always crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Semantik (semantik), signal: Segmentation fault
