OGG metadata not being saved

Most of my music is ripped in OGG format. I can edit metadata on MP3 files without any problems, and the changes are saved to the file. Editing metadata on OGG files always throw back an "unable to write metadata ..." error, no matter what field or fields are being edited.

I'm running Songbird 1.2.0 build 1146 and I'm using managed mode.
