            Bug ID: 342436
           Summary: kmail (git master) crashes upon quiting
                    window/application
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: tittiatcoke at gmail.com

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".
