Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:

Switching Task Manager icon for an expanded group of tabs to collapse it or to disallow it being grouped.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
