No, it doesn't fix the problem.

I've found that there is already a test case for that problem:
test/dropdown.cpp
It even has the comment "This sample app demonstrates a really ugly
bug".
The program crashes on exit. And valgrind clearly shows why.


What do you think of the following solution:

Adding a signal "sigDelete" to PG_Widget which is called by the
destructor of PG_Widget.
The DropDown-Menu could then hook that signal of its DropList  and set
the my_DropList variable to NULL if it is fired.
