Description kavol 2013-05-09 14:31:20 UTC 
Application: kmail (4.10.2)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.11-200.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I've accidentally closed kmail by hitting Ctrl+Q while the main window was active.
Right after that I've realised the mistake, hit Alt+F2 to show krunner then entered "kmail" and hit Enter - but instead of kmail I got DrKonqi ...

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

This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
