Hmm. Cool!

So yes.

Hmm. So it is not a `VIA problem`.

I have a Terratec Cinergy 1200 DVB-T, so no match there.

Hmm. Again no match. (thanks for the answers, though!)

EIT appears to play a certain role there. Over here the issue was 
already happening before I enabled EIT, but still EIT was in need of 
fixes at time of that graph.

Hmmm.
No VIA problem.
No Terratec problem.
No Fedora 10 problem.
What remains?

And who can run valgrind?
Can you?

Kind regards,
