Description Maxime Gamboni 2004-09-16 15:46:32 UTC 
Version:            (using KDE KDE 3.3.0)
Installed from:    Gentoo Packages
Compiler:          gcc 3.2.3 
OS:                Linux

Konsole crashes (segfault) when I try to display (unhide) the tab bar (setting the tabbar location to either top or bottom instead of hidden) AND if I am currently using a schema with a background image in centered mode.
It also crashes if the background is transparent.

Showing/hiding the menubar doesn't have that problem. Hiding the tabbar doesn't crash either. Having a background in tiled mode doesn't crash.

I tried generating a stacktrace but it kcrash says it appears unusable. I even tried to recompile kdebase with "-g" but that didn't help.

Tell me if I can provide some other info...

I ran konsole in gdb, triggered the crash and:

Program received signal SIGSEGV, Segmentation fault.
