[Natty] Gaia unusable, no gui is rendered (SimpleTileStorage: error)

[John Doe]

Binary package hint: gaia

When starting the program, I get this Output:

nordlicht@Demian:~$ gaia

The Program starts, but I don't get a usable interface. I've taken a screenshot, it shows only a grey window without any elements.
