* Bug 309464:
*
* Comment by cesken: I am not really sure what the comment above means.
* 1) IIRC coling told me "otherwise KMix crashes".
* 2) There are also bug reports that heavily indicate the crash when operation the "move stream" from a popup
* menu.
* 3) I don't know what the "executed in their own event loop" means. Are we in a "wrong" thread here (PA),
* which is not suitable for GUI code?!?
*
* Work note: Ouch. it means PA thread makes direct calls via announce(), and do even GUI code. OUCH. Redo this comments!
*
* Conclusions:
* a) It seems there seems to be some object deletion hazard with a QMenu (the one for "move stream")
* b) I do not see why executing it Queued is better, because you can never know when it is actually being
* executed: it could be "right now". It looks like Qt currently executes it after the QMenu hazard has
* resolved itselves miracously.
* c) I am definitely strongly opposed on this "execute later" approach. It is pure gambling IMO and might be
* broken any time (from DEBUG to RELEASE build, or by a new Qt or KDE version).
*
* TODO Somebody with more Qt and PA internal insight might help to clear up things here.
*
* Temporary solution: Do the QueuedConnection until we really know hat is going on. But the called code
* pulseControlsReconfigured() will then do the standard announce() so that every part of
* KMix automatically gets updated.
*
