            Bug ID: 413941
           Summary: Crash when opening Kmail
           Product: kmail2
           Version: 5.11.3
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: stuart at tase.co.uk
  Target Milestone: ---

Application: kmail (5.11.3)

Qt Version: 5.12.5
Frameworks Version: 5.61.0
Operating System: Linux 5.3.8-300.fc31.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Kmail's message window was only showing black, so I quit kmail and started it
again, only now it crashes immediately on startup before any windows are
displayed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
