Description lnxusr 2020-02-10 19:28:49 UTC

Application: kontact (5.13.2 (19.12.2))

Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 5.3.0-28-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed: Open -> Settings -> Configure Kontact and Kontact immediately segfaults.  I can't really say when this started happening as it's been a couple of weeks since I had to open the settings, but I did just install yesterdays (9 Feb '20) update a few minutes prior to trying to go into the settings.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

New crash information added by DrKonqi

kontact (5.11.3) using Qt 5.12.4

- What I was doing when the application crashed:
Kontact crashed as soon as I opened its settings.

- Custom settings of the application:
Not application specific, but I configured kwin to show an application menu button on the title bar.

*** This bug has been marked as a duplicate of bug 415634 ***

Comment 3 Wolfgang Bauer 2020-02-16 12:23:09 UTC

The original creash in bug#415634 is something completely different.

This crash here seems to be caused by this change in kcmutils 5.67.0:
https://cgit.kde.org/kcmutils.git/commit/?id=f52314e6cf194c64edd331a98a31803bbd971484
Reverting this fixes the crash for me.

Check activeModule before using it

`activeModule` can be a nullptr here, as this is outside/after the
`if (activeModule)`.
This causes kontact to crash when opening its settings.
