As far as I can tell, Banshee has been broken for at least a couple version releases of Fedora now. It had an issue with randomly crashing a while back, but currently it just can't seem to play MP3 audio at all.
I have all the usual suspects installed for MP3 support, and it works on all the other apps, but not in Banshee.
$ rpm -qa banshee 'gstreamer-plugins-*'
When attempting to play an MP3 from my playlist, Banshee instantly refuses (shows an X symbol next to the track), runs through the list and tries the next 4 songs before finally giving up completely. Nothing is written to the console output for any of this; how can I determine what the problem is?
I'm using the XFCE spin of Fedora 19 and I see this behavior on multiple computers, and also saw it on Fedora 18 XFCE. I hope Banshee didn't become completely dependent on the Gnome desktop? It can play ogg files, just not MP3.
