Bug 179682

Version:           2.1 (using KDE 4.1.3)
Compiler:          gcc 4.3.2 
OS:                Linux
Installed from:    Ubuntu Packages

Opening a tab for the konsole session segfaults & terminates all tabs & windows for that session.  Opening a new window instead doesn't do this (although opening a new tab in the new window kills both windows).

Here's a stack trace.  Note that the kpixmapcache.cpp:643 line repeats indefinitely(with the all the same values).  I did a "where -1" to try and see what originated this, but my computer was chugging away full-speed for like 5 minutes before I gave up.

Strangely, this only happens with my laptop (Ubuntu) & not on my desktop (Kubuntu).  I've tried blowing away my .kde profile, but that didn't help.  This is reproducible every time which is really annoying cause I got used to opening tabs.
