[kde-linux] konqueror crash

[pol]

Hi all, 

After a couple years working perfectly, kde session restoring begun to 
fail a few weeks ago, on my debian/testing laptop.
At the user session opening, every konqueror instance, saved in the previous
session, crashes. Here included the backtrace, from the crash window panel.
lHowever, any new konqueror instaces start flawlessly.
Any idea?

thank you for your help
