Emacs hangs up.

[David Kastrup]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

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

When editing (maybe switching workspaces that caused something to get
obscured or shown), Emacs suddenly hangs: no window updates, no
reaction.  I have had this quite a few times already.

Here is a backtrace:
