Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.2.2 

So.. I had about 8 konqueror windows in kicker, some of those had been running for some time, a couple of file browsers and the rest were web browsing. I asked kicker to close them all and it left one of them crashing. 

Though I seem to have one konqueror process to be left running background I am pretty sure that many processes were told to close in this situation. (I launched many of those from the kicker's icon and the load times were 7-8 secs so it must had launched a new process).

Any questions I'll be happy to answer. Not sure of the reproducability at the moment. Qt is latest 3.2.2, konq/kdelibs are less than 48 hours old from anoncvs.
