KDEVELOP_1_4: SegFault crash after closing all windows

Falk, 
there is a bug in current CVS that leads to the following segfault. 

It happens when I close all windows and try to open a new window. 

I suppose that m_firstFocusableChildWidget is actually not valid any
longer but see for yourself. The crash is reproducable. 

Greetings,
Roland
PS: I havent heard from you for a while, drop me a mail if you've got a
minute
