failing IMAP on Lotus Notes domino server

["Kacper Wysocki" <kacperw online no>]

Hey folks,

I've been travelling and moving a lot this past year, and so I've
preferred web-based mail over balsa. However I now have a new job, and
with it, a new mail system based on lotus notes. Since Notes is shite
on linux and the web gui is less than optimal, I managed to get IMAP
access to the thing.. but something is rotten in the state of imap:

I can log in and fetch a list of messages, but when I try to open a
message I get

Could not access message 117 in mailbox "inbox".

This is with balsa 2.3.8-1ubuntu3. I know you love to hear this, but
mozilla thunderchicken seems to have no problems with the domino
server.

After turning on debugging and starting balsa with -D, I get the
following console output when opening a message (sensitive info taken
out with [...]'s):

Any suggestions for further debugging?
