Review request for Dolphin.


Bugs: 354558
    https://bugs.kde.org/show_bug.cgi?id=354558


Repository: dolphin


Description
-------

Do not delete sub menus of the control menu explicitly
    
This is not necessary because the sub menus are children of the main menu, such that they are deleted together with the other actions by QMenu::clear().
    
This prevents a crash that can happen if a sub menu is open while another menu action is clicked.
    
Thanks to Fabian Vogt and Wolfgang Bauer for investigating this issue!

Testing
-------

Verified that the crash is not reproducible any more, and checked with Valgrind that this does not cause any memory leaks.


Thanks,

Frank Reininghaus
