Unfortunately, with qt-copy/HEAD from 12 hours ago, the example still crashes 
for me without application of the patch (with the same backtrace). However, 
Noatun and kopete don't crash anymore. Could this be something specific to my 
setup? I am using gcc-3.2 on RH8 with self-compiled qt-copy/HEAD. Running 
"ldd" on my application shows that it is linked to the correct libraries.

Also, without the use of KJanusWidget, I don't have the problem if I manually 
create a QWidgetStack and delete objects therein. AFAICS, there is nothing 
special being done in the implementation of KJanusWidget, and I am at a loss 
to figure out where the problem is. Your help is greatly appreciated. As a 
temporary workaround for my application, I am using a local copy of 
KJanusWidget (renamed as FJanusWidget) with the patch applied for which the 
code works.
