Yes, testing on sfcb.

Well, yet another difference between Pegasus and sfcb. Pegasus seems to 
take the given object path, do an enumerateInstanceNames and iterate 
through the returned instances trying to find the requested one. This 
error_not_found is definitely created by Pegasus itself, while the 
getInstance() of our provider does not get called in this case. On the 
other hand sfcb directs this call to the provider (that's why he can 
call himself "small footprint" ;) ).

I will have a look into it and try to find out where it segfault.
