Version:            (using KDE KDE 3.4.0)
Installed from:    SuSE RPMs
OS:                Linux

I'm not sure what is causing this bug, it seems to have no pattern to it, other than a few common factors.

In all cases, I was using kaffeine to view WMV streams in the browser window.  Sometimes Konqueror SIGSERV'd when I clicked the back button, sometimes when I wasn't even viewing a stram, and clicked to change pages.  It only ever crashes when I click.

The page I was viewing is http://www.plsthx.com

Reproducable? Definitely, although it is random, it usually happens about every 5 minutes.  One time it was about 30 seconds between crashes (reloaded in between).

Other programs running: Kopete, and Kaffeine main screen.

Sorry I can't be a little more specific.
