I am using version libqt3-mt 3.3.6-1ubuntu6 (standard from Kubuntu Dapper).
I have applied your patch to qt3 example and it does not emit
selectionChanged() when dragging, only when clicking.

This is not a problem in Python or messagebox. I have noticed it in C++
library using kdDebug(). I just wrote the testcase in Python to make it

So, can anyone else verify this on their version of qt? If it appears
only on Ubuntu with its qt, I will file a bug on Launchpad.
