Hmm.. Now, KDE apps are crashing all over the place - KCMInit,
kded4, KTorrent, Akregator..
Initially, some reports indicated its a glibc bug. But now it does seem
to be an nvidia bug.
The strange thing is, first glibc and then nvidia both claimed they fixed
this bug, but neither fix seems to have fully solved the problem.
I can only recommend using Nouveau instead.
