Description Szega 2018-12-06 15:35:39 UTC
Application: kmail (5.7.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-42-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I closed KMail

- Unusual behavior I noticed:
Seg Fault.

Using QtCurve widget style with transparent app background causes the crash.
If I select any other style, KMail exits normally.
(Could be related: Double Commander-qt also doing this)

The crash can be reproduced every time.

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