wine debug file

Hello there.

Ubuntu Studio 18.04 (XFCE), Native Instruments Kontakt (every version : can
reproduce with K4, K5, K6, free or full version, and also with old wine
versions or ubuntu versions.

Not happening on Windows.

The drag/drop from desktop to Kontakt crashes in some cases : when I drag a
file from Thunar to Kontakt, it gives (normal behavior) a popup representing
the process of loading samples in Kontakt. But I cannot interact  with the
windowed popup, and it result to a freeze if an action is needed in this popup.

The same action can be done from Kontakt to Kontakt without any problem.

Here is a debug file.
Most probably the moment when problem appears is at line 356 :
fixme:xdnd:X11DRV_XDND_DROPEFFECTToXdndAction unknown drop effect 0, assuming
XdndActionCopy

Regards.
