Jorg, I think the problem is that you are not wrapping your Metadata
dict in a variant.

The problem is that my generated C code is expecting the dict to be in variant.
The interface definition in Vala is type as a hashtable but the C code
automatically assumes everything has outer wrapper layer of a variant. Take a
look at the rhythmbox or banshee and see what they return over d-feet. its the
same code on my side that handles all clients and its just yours that's is
crashing my service.
