Review request for KDE Multimedia and Christian Esken.


Description
-------

The crash, described in the referenced bug, seems to be caused by deleting menu objects from menu action handlers, since KMix completele rebuilds UI elements on reaction to stream move. By changing signal connection type to QueuedConnection, we just scheduling move from the handler (which is always called via user input event). Thus, UI rebuild will happen later and crash is avoided.


This addresses bug 311167.
