Review request for Plasma and Marco Martin.


Summary
-------

In some situations (KPackageKit KSNI comes to mind), the KSNI is deleted when the user right clicks it. While the behavior of that application is questionable, it should not crash the workspace.

The change here ensures that the menu is showing asynchronously. It prevents a random crash which I uncovered after fixing the original issue of bug #241562 (see http://reviewboard.kde.org/r/6022/ )


This addresses bug 241562.

Testing
-------

Right-clicking KPackageKit KSNI would cause a crash one time out of three before this patch. It does not crash anymore now.


Thanks,

Aurélien
