Description Raymond Wooninck 2015-01-03 12:31:21 UTC

Application: kmail (4.73 pre)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-rc2-2.gcd0d0f3-desktop x86_64
Distribution: "openSUSE 20141230 (Tumbleweed) (x86_64)"

-- Information about the crash:
Kmail is running fine throughout the session, but crashes when a kmail window is closed. This can either be an email opened in a separate window or if the main window is closed.  Closing in this case is NOT equal to minimizing, but really quitting the application/window.  

This happens everytime and it reminds me of a bug in the 4.14.x series, which was resolved quite some time ago by David Faure. 

This is with all kdepim related libraries from master and running the latest KDE Frameworks from git.

The crash can be reproduced every time.

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