First of all, thanks for sharing the workaround! I'm not familiar with
the X11 drag&drop stuff, so I cannot comment on it.

You said that a patch is in the Qt bug tracker, but all I could find
with a bit of searching is a link to this Chromium report, which has a
patch:

https://code.google.com/p/chromium/issues/detail?id=543940

Is that the patch you mean? Do you know if it has been submitted for
review to Qt? If not, do you think that you could make that happen
(since you seem to know quite a bit about drag&drop) or help to make
it happen?

Thanks,
Frank
