I have tried it with Python-2.5, Qt-4.2.1, sip-snapshot-20061126, 
PyQt-4-snapshot-20061129. On all platforms, drag move actions work as 
expected, but drag copy actions show a wrong behavior (compared to the 
behavior of the Qt example): After starting a drag copy action, the icon 
is grayed at the old position. After a drop, the gray icon should 
disappear and the normal icon should appear again, but the grayed icon 
remains. Sooner or later, the application crashes on most platforms.

On Linux (SuSE 9.2) it crashes.
On Solaris it crashes.
On AIX it crashes.
On HP-UX it doesn't crash.
On IRIX it crashes.
On Windows it doesn't crash.

After applying the changes suggested by Mancausoft, everything works as 
expected. If these changes make no sense Phil, there must be something 
wrong with PyQt or SIP.
