Description Volker Kuhlmann 2013-08-12 06:24:14 UTC 
Application: kmail (4.10.5)
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

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

Exited kmail with ^Q intentionally, but the process didn't exit.

Then I noticed I still had a composition window open - oops. I finished that email and sent it - the notice in the Notifications was that it was successfully sent. I was then expecting the kmail process to exit.

When it didn't, I started another kmail, and got drkon

It appears the newly started kmail crashed.

I have the same problem: KMail does not terminate its process when I close it. Also Kontact with KMail does not terminate too. If I attach with GDB to such a kmail, it shows the following:

Comment 3 Eugene Shalygin 2014-02-12 18:44:24 UTC 
I believe that the cause of the problem is here, but not in the bug 319574, i.e. that KMail does not terminate correctly
