Bug 298881

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-2-amd64 x86_64
Distribution: Debian GNU/Linux testing/unstable

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

- Unusual behavior I noticed:

The taskbar only shows the icon application and besides, when you hit Alt-Tab th applications running appear with a small icon and it's name instead the new style.

Also when you are switching from an app to another, the upper of the corresponding window goes to black  and after the application came to the front, the upper bar takes the appearence of the KDE's theme that is in effect in that moment

-- Backtrace:
Application: Shell de escritorio Plasma (plasma-desktop), signal: Segmentation fault
