I'm having exactly the same problem.
To demonstrate, consider the artist blanck mass
As you can see here in my player, the metadata is A+

So lets search for it in subsonic:

Ok...so that's weird. What is happening. Well, the filename is being interpreted as the ARTIST. I have no idea why that would be, but it appears to be true.

BUT, the artist is also being listed correctly in playlists. So I'm not sure what curious voodoo is going on here.
I have rebuilt my Database twice, and what I share with mboonie above is my files are hosted on nas.
Below are errors in the main log:

I actually allocate 2Gigs of memory to subsonic, so I'm note sure what is causing the allocation failures or even if they are related.
This is the startup line.
