[Dharma Beta 3] XBMC hangs after finishing Music playlist

Hey guys

While working with the JSON RPC API I ran XBMC (on my secondary screen) and listened to a music album in Music Visualization. Because I hadn't done anything in XBMC for a while the screen went black (my screensaver settings) and then the last song in the playlist finished. After that I tried to reactivate XBMC by Alt+Tab'ing and clicking into the window but nothing happend. So I killed it using the Task Manager. When I restarted XBMC I was in Confluence (my skin is set to Night) so I went into the Appearence settings and wanted to change it back to Confluence. But the Skin setting was already set to skin.night. But when I clicked it to see the list of available skins I only got Confluence but no Night.

So I pastebin'ed the XBMC log here: http://pastebin.com/iBK6WUQ6
Unfortunately it's no full debug log as I didn't expect it to do something crazy.

I also checked if anything else got missing but only the skin.night plugin is MIA (or rather KIA). There is still a skin.night folder in my AppData/Roaming/XBMC/addons but not in my XBMC installation directories "addons" directory.

If you need more information let me know and I'll try to provide it.
