mairix problems

[prad]

i've been trying to get mairix working today and it does (works great
from shell (superfast on 2G) - but i can't see the results with nnmairix.

there is ~/Mail and ~/Mail/inbox (cur/ tmp/ new/ and dovecot indicies)

in .gnus:
(require 'nnmairix)

in .mairixrc:
base=~/Mail
database=~/.mairixdb
mfolder=default
maildir=inbox
mformat=maildir
omit=zz_mairix-*

then setting up the group with G b c
name of mairix server: test
back end server: nnimap:Mail
command: mairix
default search group: def
work with maildir++: yes and no -- doesn't seem to make much difference

this produces a group:
nnmairix+test:def

what happens is that i do a search with G b s and it finds the 60 items it
is supposed to (verified by doing this on the shell).

the links go into 
~/Mail/zz_mairix-def-*/cur/ (maildir++ is no)
~/Mail/.zz_mairix-def-*/cur/ (maildir++ is yes)

and always there is created ~/Mail/inbox/.zz_mairix-def-*/ with
cur/
new/
tmp/
dovecot.index.log
dovecot-uidlist
maildirfolder

however, i can't go into the group
nnmairix+test:def

nor does it come up automatically as indicated in the manual:
"Prompts for query which is then sent to the mairix binary. Search
results are put into the default search group which is automatically
displayed"

so it seems i'm missing a piece somewhere since mairix is doing its job
both out of gnus and in it. what can be done?

(btw, i also tried nnir with imap, but couldn't get the group to open -
but that's another story)
