[packman] xvidcap stability

[madworm_de.packman at spitzenpfeil.org]

Here's the strange thing. I have 2 user accounts on my machine that can use xvidcap more or less reliably, only very few crashes. If however I create
a new user (same group membership) and even try to use xvidcap it crashes as soon as there is too much movement in the recording area. When crashed
the frame-counter stops and the application is frozen.

I tried to disable desktop effects, but that doesn't help at all. The "good" users have them activated anyway. I use openSUSE 12.1 + KDE.
