--- Comment #2 from Johannes Rauh <jar...@web.de> ---
I have precisely the same problem. For me it happens not always, but
sometimes. Here is my crash report:
Application: kwin (4.11.13)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-686-pae i686
Distribution: Debian GNU/Linux 8.2 (jessie)
-- Information about the crash:
- What I was doing when the application crashed:
The following is not happening always, but already happened several times:
1. I finish an email with Thunderbird and click on "send".
2. While Thunderbird is still sending the email, I am pressing ALT+TAB to
select another window.
3. While I am still wondering which window to select next, Thunderbird finishes
sending the mail and closes the window.
4. At this moment, kwin crashes.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
