Hi guys !

I got a problem when closing a window ( a QMainWindow ) in an MDI widget. Here 
are the files that cause the problem. It's a segmentation fault

And here is the output :
Destructor called : closing channels and sending QUIT cmd to serv
Destroying #gentoo
item removed
Leaving #gentoo
unregistering channel
channel unregistered
Part cmd sent
item destroyed
Segmentation fault

Thanks for help,
Alex
