        Hi,
this is interesting. I noticed it only now, after checking the code
slightly more closely. The LIST command, which the server rejects,
contains the 'RETURN (...)' part, which is supposed to be there,
according to the code, only if the server advertises LIST-EXTENDED
capability, but the server does not advertise it, it has only the
LIST-STATUS capability, which is responsible for the 'STATUS (...)'
part of the 'RETURN (...)' part.

In other words, without the 'LIST-EXTENDED' capability there should be
no 'RETURN (...)' in the LIST command.

I'll investigate and test this further, I did not notice anything
obvious on a quick code read, and I will update the following bug with
my finding (it'll be moved to the evolution-data-server, where the code
resides):

        Bye,
