Review request for KDE Base Apps and Eike Hein.


Repository: konsole


Description
-------

When containers are destructed, they emit a signal that the splitter is connected to which removes and unregisters the container from the splitter.
A crash happens when the splitter is destroyed before the container, so a slot in a deleted splitter is called, tries to unregister the container, and segfaults.
I added a destructor to ViewSplitter which unregisters all it's containers, this fixes the crash here on closing of a tab in yakuake and on closing a tab in konsole.

Testing
-------

Manual testing, it seems to work fine.


Thanks,

Jeremy Whiting
