Description Remigiusz Marcinkiewicz 2005-02-27 01:32:51 UTC 
Version:            (using KDE KDE 3.3.2)
Installed from:    Slackware Packages
OS:                Linux

Konqueror crashes on pure-css popups at http://www.rootshell.be/~upadhyay/2005/01/more-fun-with-css-popups.html
Just click on the first link in the text, labeled "hiding". Seems to be 100%-reproducible, but I have no idea what exactly causes KHTML to crash.
I'm afraid I can't afford recompiling KDE to give exact backtrace, but as it's fully reproducible (I've asked several people on different Linux distros to check that, all of them are getting segfaults), you should be able to get far more accurate debug information than me anyway.

Just checked: it's present on KDE 3.4beta2 too.

Confirmed, but it required some moving around.
