[dovecot] problem with COPY?

[JP]

hi all,

I've been trying to use dovecot (from cvs 03.mar.2003, linux 2.2.20,
gcc 2.96, openssl 0.9.7a) as an replacement for uw-imap, and it seems
to be doing its job, except for one thing:

I have my mua (sylpheed-claws from cvs) set up so that it will sort
message into certain(imap) directories. so when I check the mail in the
INBOX, new mails will be processed automatically and, for example spamcop
related emails are moved to their own 'folder'. imap session below.

[STARTTLS and LOGIN stuff not included... no errors whatsoever there.]

now after this, the conenction goes unresponsive and the following appears
in the server log:

Mar  4 18:06:42 btp212 imap(jp): file index-save.c: line 61
(write_with_lf): assertion failed:(size > 0 && size <= SSIZE_T_MAX)
Mar  4 18:06:42 btp212 dovecot: child 6022 (imap) killed with signal 6

any ideas on what might be causing this? dovecot/mua/some else?

regards,

JP
