           Summary: crash when opening a new tab using
           Product: konsole
           Version: 2.1
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: vlovich+kde at gmail.com


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.
