Konqueror crashes sometimes when moving backwards. You can reproduce crashes easily by going to:

http://www.imdb.com/name/nm0324409/

clicking on a photo (yes, she's gorgeous) or movie (filmography) link and then moving backwards.

I found this bug posted in Kubuntu mail list and launchpad with no feedback.

Loaded plugins:

-Java Plug-in KJAS for Konqueror (kjavaappletviewer.so) (openjdk6 1.4)
