Wine log for xdnd

Operating System: Kubuntu 8.10 with KDE 4.1 / i386 / nvidia grafics

While running any wine-application its impossible to drag & drop files to. For
exampe: Starting up 'notepad.exe' from the wine package. Then drag&drop a text
file from konqueror or dolphin (both doesn't work) to the notepad-window. But
the file won open up in notepad; but then I got the message from notepad >"
could not be found<.

So what happened? On my old system with KDE 3.5.10, everything is working
fine... so i looked a bit closer and logged the output of wine for xdnd (see
attachement). The problem can be isolated to the following lines:

KDE 3.5.10 wine notepad.exe trace of xDND reveals:
trace:xdnd:X11DRV_XDND_SendDropFiles Sending WM_DROPFILES: hWnd(0x0x1002a)
0x1e524c(Z:\home\gizmo\test.txt)

But in KDE 4.1:
trace:xdnd:X11DRV_XDND_SendDropFiles Sending WM_DROPFILES: hWnd(0x0x1002a)
0x2454354()   <= here missing target !!!

The bug occurs because the target (file) is missing at WM_DROPFILES.

Please someone fix this, because i concerns all wine application and leaves
them without drag&drop support on KDE 4. Thanks :-)
