If I understood you right, this would be the same in Gnome, which in fact
isn't. Or is Gnome handling (because of the X-server) the keyboard in a
different way?
My speech is configured to speak very fast, hence I hear all keys I press (I
can't verify, but distinguish them). When this problem occures the speech
stops for felt milliseconds and then begins reporting the repeated keys
and the keys which I pressed afterwards. However, this is only how I think it
happens.

You could also write a little patch which I apply for testing. Then I send you
the relevant output from the log file.

So I guess it might be a hardware problem. thanks and sorry for the time wasted
on it.
