It could very well be the case, yes. In my case (since I guess I'm the
friend Stefan was talking about) it happened with KDE 2.1, lasted
something like 5 seconds and did not happen with other WMs (I tried
Gnome's, KDE 1's, and a few others).

Back then, I had obtained the following backtrace by interrupting
Emacs during the delay. Maybe it can help the original poster...

I cannot reproduce the problem with my current version of KDE, though
(2.2.1).

Michel.
