I know I'm late to the party, but I ran into this problem also. EOF creates a backup ogg, so you can delete the 3 second long song (guitar.ogg) and rename the backup to guitar.ogg. That should recover the work you've done. I still don't know how to get it to work, but I think it has something to do with the bit rate. Songs I've done with 192k bit rates worked fine, but all those I've done with higher bit rates failed. That is probably not a coincidence.
