It used to happen every time a started totem or banshee. The
application would spawn gst-plugin-scanner which would not return,
causing the application to hang. If I killed the gst-plugin-scanner
process, the application would continue and work. It even worked after
closing and reopening it -- for some time, then the same would happen
again.

The strange thing is that the problem does not appear any longer. (At
the moment, at least.) It seems to have vanished at the time I removed
package "nvidia-96", that's NVidias proprietary driver for legacy
cards. Some of our clients run such cards, that's why we had it
installed. Now NVidia's drivers do not co-exist well with other X
drivers, basically, they replace a library with an NVidia specific
version, breaking the other drivers.
I did not notice that this was the case with our installation until
recently. After I had removed "nvidia-96", I noticed that the runanway
gst-plugin-scanner processes were gone.

Of course, the two things could be completely unrelated. However,
there is at least one other report that sound broke after installing
NVidia drivers, here:

I do not know what to make of it either. It might be pure coincidence,
but then I cannot think of anything else I have changed.

Best,
Rüdiger
