dovecot - Oct 2012 - doveadm purge -A via doveadm-proxy director fails after some users

# 2.1.10: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-44-server x86_64 Ubuntu 10.04.4 LTS 

doveadm -c /etc/dovecot-director/dovecot-director.conf -D purge -A
shows the following message in the log when iterating the 49th user:

Oct 17 00:47:17 10.129.3.233 dovecot: doveadm: Error: purge: invalid option --
'e'
Oct 17 00:47:17 10.129.3.233 dovecot: doveadm(someuser at example-ll.org):
Error: doveadm purge: Client sent unknown parameter: ?

Any ideas on how this error gets triggered?

Regards
Daniel

Not sure. There's no valid 'e' option anywhere. I guess one of the
non-option parameters begin with "-e" and it think it's an option.
But I can't really think of how that would happen with purge either. So it
would be helpful to look at what exactly the doveadms are talking to each
others. Could you get the network traffic from them? Or strace -s 1000 doveadm
purge should show it somewhere too.
