New crash information added by DrKonqi

Hello:

I have this same bug with konqueror on KDE 4.4.5, not that I can provide much information yet, but I thought it may help knowing this for the record.
Comment 3 Raúl 2011-04-29 11:20:49 UTC

Valgrind log.
Comment 4 Raúl 2011-04-29 12:28:10 UTC 
Created attachment 59419 [details]
Saved session file trigerring crash.

Steps to reproduce:
1- Make sure you cleanly exit konqueror so ~/.kde/share/apps/konqueror/autosave dir is empty
2- Copy attached _1.2786 file to ~/.kde/share/apps/konqueror/autosave dir
3- run konqueror (preferably on a konsole)
4- Let it load and see the crash.

If the crash you have is not the one from this bug, just exit DrKonqi normally and repeat steps 3 and 4.
