Version:           CVS (using KDE KDE 3.1.2)
Installed from:    RedHat RPMs
Compiler:          gcc 3.2.2 
OS:          Linux

I am using gideon in Ideal mode.
In yesterdays CVS build I get a new crash:
Opening the tab bars either using the menu entries (view->switch .. tabbar)
or the hotkeys produces a crash.

Probably related to the replacement of the tabbar text tabs with icons somehow?
BTW, is/will there be any way to choose the old style text labels? 

My stack trace:
