Description invictustiberius 2019-08-22 04:07:25 UTC 
Application: kmail (5.12.0)

Qt Version: 5.12.3
Frameworks Version: 5.61.0
Operating System: Linux 4.15.0-58-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed:
Clicked on KMail icon on system tray to show its window (previously closed to systray, not minimized)

- Unusual behavior I noticed:
KMail crashed, leaving Dr Konqi notification to Restart Application or send this bug report.

- Custom settings of the application:
Enabled systray icon.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault

Not happening anymore. Seems like it only happened when using Kvantum themes, but now it works fine, so I think it's fixed.
