Hi,

 Today I played with Xgl and compiz and there are two annoying bugs:
- sometimes menus stop to appear (especially after 
connecting/disconnecting to the internet using kppp)
- kicker crashes on disconnect from the internet


The latter one at least gives me a backtrace, so there is a bigger 
chance to find what's wrong:

Using host libthread_db library "/lib64/libthread_db.so.1".

kdeui/qxembed.cpp:1060 contains: "if( !d->xplain )".  This cannot crash 
only if d is NULL or there is some other memory corruption before. d 
cannot be NULL, only if the QXEmbed::x11Event( XEvent* e) is called 
*after* the QXEmbed object is destroyed. 

My question: can this really happen or the problem is at completely 
different place, just that it appears here?
