Android Question MediaBrowser: no media on the device!

I keep getting these messages from MediaBrowser.

I've believe I have tracked the problem down to being this:

I sometimes my path / file names are all lower case and when I call MediaBrowser with a path that does not match the case of the real path / filename I get this error.

Below gives "no media don the device!"
/storage/extSdCard/music/various artists/now that's what i call music!/volume-17/16 - pieces of me.mp3

This does not:
/storage/extSdCard/Music/Various Artists/Now That's What I Call Music!/Volume-17/16 - Pieces of Me.mp3

Is it possible to turn off this MediaBrowser message?
