Hi,

I'm getting some strange (reproducible) crash in konqueror.

Try the following: start konqueror, then enter slashdot.org
into the location bar.
After loading of the page wait until the message
kdecore (KLibLoader): closing library libkonqiconview 
appears, and the enter spiegel.de into the location bar.

It's not related to the URLs as far as I could tell. Everything works
fine, if I enter the second URL before libkonqiconview is closed.

I've attached a log of the session and a gdb backtrace. It doesn't tell me
much, except that konqueror tries to access some dlopened lib. My guess is
that it for some reason tries to access a method in the closed down
iconview lib.

Anyone an idea?

Cheers,
Lars
