Hi all,

I've just ran into an issue regarding the automatic skipping of already known unplayable tracks (just did a touch to 
create some files). In my use case i had a tracksession consisting of ONLY unplayable tracks. If I fire a 'mmecli 
play_extended offset 0' on this tracksession, the mme skips as assumed from track to track with the message:

 'Skipping file because it is known to be not playable. fid=251, filename='/net/mmx.mibhigh.net/fs/sdb0//Gemischt/error 
testing/only corrupt files//3empty.mp3'

Unfortunately the mme doesn't recognize the end of the tracksession and therefore loops until forever. At this point the
 mme is unresponsive as well. So it's not possible to call a stop or any other command.

There are eleven entries within my tracksession:
