Yep, this leads to a crash even for me, but not to the one mentioned
above:

I get this crash even when I only start konqui in homedir (iconview), and
quit it. Seems some unclean things in the toolbar or xmlgui code. It also
happens when I disable the dlclose. So this crash is not connected with
unloading. The one in _dl_lookup_symbol() is, but I can't reproduce it, as
the above SEGV is faster ;)


Ciao,
Michael.
