NPE on upgrade to 0.70

[bubbleguuum]

Hi Simon,

I upgraded from an older version to 0.70 on Windows and got the NPE below which I solved by removing miniserver's data directory to start from scratch.

To give more context on how it happened, the previous version of minimserver had 3 contentDir like this:
C:\Music\Labels
C:\Music\Lossless
C:\Music\blargh

This was not correct as I had moved these folders to G: and blargh had been deleted, so I changed the list to be

G:\Music\Labels
G:\Music\Lossless

minimserver rescanned the files but failed to launch on NPE above.
My guess is that it is due to the removal of that blargh contentDir =).
