I have seen and read about problems with libxcb when (Q?)Xembed is used. That 
might be relevant here. They seem thread-related (known problems with xine in 
the past, which uses embedding, and I've seen similar a while ago when I had 
experimentally built qt4 with libxcb and in both kbtv1 and kbtv2 if the video 
was playing in the embedded SDL viewer, if I would for example resize a modal 
window it would crash. I'm afraid that the libxcb (freedesktop?) people got a 
little too enthusiastic when exterminating X threading problems (when more 
than one thread touches the same screen item) and this may not be entirely 
made fallout-free. What I mean is that properly threaded apps using embedding 
(and thus are itself responsible for thread safety -- not X) may be 
considered faulty by libxcb leading to crashes.

I'm not sure if that is or will be relevant in a KDE4 context, but I would 
like to let you know what I've gathered about this. It may be a potential 
problem and we get to see systemic problems with (Q)Xembed then this is one 
place to look.
