Well, for a QListView you won't get notified when the drop is finished.
The QListView just moves it's internal QListViewItem to the new visual
position, not signals emitted..

I don't assume that anymore, for any error that is not obviously in my
code. For any "weird" behaviour I try to build a minimal example, post
it on qt-interest for a few days and then send bugreport to TT. We can
only hope that Qt4.2 will have a _lot_ less bugs, especially as KDE4 will
be built on top of it.
There was a phone call for you.
