 I'd expect the difference is merely in the window manager. When running full 
KDE session with E instead of KWin you'll probably have the same problem too.

 The problem would be hardly trivial to debug or fix, it can be in many 
places, maybe Qt's DND handling code has a bug, maybe the bug is somewhere in 
E. Moreover DND implementation is relatively low-level X stuff, nothing 
simple. The Qt code in in qt/src/kernel/qdnd_x11.cpp, that should be the 
place to start finding out why it doesn't work.
