Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 7.0 (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
Right before the crash I tried different settings for the list of windows shown on the window bar ath the bottom of the screen.
- Unusual behavior I noticed:
The buttons which grouped several windows showed the title of all grouped windows at the same position instead of only the title of one. So the text became unreadable.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation fault
