The tags in m4a files are read by the qtdemux plugin which is actually
in gst-plugins-bad.  Which version of that package are you running?

You can see if qtdemux is getting the wrong m4a tags by running the
following command-line pipeline (the "-t" option displays the tags):

gst-launch playbin -t uri=file:///path/to/somefile.m4a

You should see something like:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
FOUND TAG      : found by element "qtdemux0".
     audio codec: MPEG-4 AAC audio
FOUND TAG      : found by element "qtdemux0".

This will at least tell if you the qtdemux gstreamer plugin is getting
the genres wrong.
