Problem getting headers of an IMAP account

[Sergio Villar Senin <svillar igalia com>]

Hi,

I've been getting this error when trying to recover messages from a
folder of an IMAP account:

camel-imap-provider-WARNING **: Problem while receiving headers from
MMAP (I didn't receive enough headers 0 vs 9)

Looking deeper into the code it seems that in
camel_imap_command_response I'm getting the following response from the
imap server:

A00012 BAD Invalid field-name in UID Fetch BODY.PEEK[HEADER.FIELDS

Any clue?
