x-dnd (drag and drop) fails on x86_64

[Reiner Steib]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Open www.gnu.org in the Firefox browser.  Select some text
(e.g. "Welcome to the GNU Project web server") with the mouse.
Dragging the text over the Emacs frame leads to the following
backtrace:

Emacs was built on x86_64 (AMD 64 bit) and started with "emacs -Q",
then I did `M-x toggle-debug-on-error RET'.  Drag and drop to an Emacs
built on i686 (same source) works fine.
