i reviewed the files in question:

i ran the tagger for a selection of different genre files in a seperate 
directory with no visible errror message, but id3v2 -l doesn't show any new 
tag. So it might be that the tagging is broken and therefor things don't work.

gstreamer and its plugins are installed, what now?
