Music Library plugin disables hibernate.

[acheyne]

If I use the Music Library plugin to listen to my music, my system stops hibernating properly. If I exit PVRX2 and restart it, my hibernation settings start working again.

Some other notes:

- GBPVR 1.1.5
- playing music from a network mounted drive.
- making sure I actually press Stop before returning to the Main menu.
- Video plugin points at the same network mounted drive, but never has this problem.

Thanks for any pointers!
