[maemo-developers] Assertion failed unexpectedly

[From: Jakov]

Oh my God! I didn't realize that for a long time! This morning after such a
stupid prob, I removed maemo 4.0 and installed Maemo 3.2. Not tested yet,
but I think it should have the same params counts as you say. I'll tell you
the result soon. Just a quick msg now to say thank you! Thanks so much,
Markku Vire!
