All dialogs create new widget but seemingly never delete them.

In fact they do. Take a look at Widget destructor. It will
call delete on next widget in widgets chain which
effectively destroys all children.

Only problem which could be with our GUI code is when widget
is recreated on each resolution change, and particularly
ListWidget had this bug. It used to add yet another
scrollbar on each resolution change.

Hmm, strange. MallocDebug was definitely showing a leak but,
of course, I can't reproduce it now.

Either way, as you rightly state, my patch was wrong.
