[MeeGo-touch-dev] trying to delete an MApplicationPage

[Daniel d'Andrada]

Hi,

Didn't really get your second paragraph.
In any case, calling "delete myPage" should just work unless you're 
calling it from within a slot activated by a signal emission from myPage 
itself.

Thus please file a bug with a small code snippet showing what you're doing.

Thanks,
-Daniel
