I have been running OMP in a terminal since I mentioned the issue again (post 1327).
This "Now Playing disappearing" happened again yesterday but fortunately while the screen was on and I was looking at it.

Nothing comes up in the terminal so there no debug information in text form.
However it happened when:-

*Receiving a text message with the screen unlocked and on after just sending a text. Only Terminal / OMP where running, display at the task switcher.

*I had just put the device down on a flat surface, it was starting to rotate to portrait from the text I just did in landscape.

*hildon-desktop restarted.



After the heavy CPU load of the hildon stuff restarting then the Now Playing menu jumped back to Artists.

I know there's a lot of irrelevant information here. I am trying to be as verbose as possible. It has never happened on a text before normally it's calls.

I have tested restarting h-h/h-d/h-s-m while OMP is open and cannot reproduce.

Hope this helps.
