I don't think it's that tricky. There's only a few places where 
content_type is/can be set:

- the default declaration at class level (-> 'unknown/unknown')
- during __init__ where self.__dict__ is upated from the .metadata 
properties
- during FSFile._readFile where the flawed computation happens.

I believe correcting the computation in FSFile._readFile to consider 
the .metadata file first should do the trick.
