Crash when undocking output tools window

[Simon Woodward]

To reproduce:
1) Go Options->KDevelop Setup->UI
2) Set the mode to Toplevel mode, hit OK
3) Go Options->Kdevelop Setup->UI
4) Set the mode to Tab Page Mode, hit OK. (this, incidentally, redocks all 
the output tools - very useful.)
5) Attempt to undock the output tools tabbed window by dragging.  A 3 second 
pause, and Kablooey!  SGSEGV.  

I've included the call stack.
