            Bug ID: 401829
           Summary: KMail crashes every time while closing
           Product: kmail2
           Version: 5.7.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: kop98kop at freemail.hu
  Target Milestone: ---

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".
