[Dovecot] dovecot-1.0-test27 crash on FETCH

[Wouter Van Hemel]

Hello,

I've got a crash with -test27 on a FETCH, just after logging in. Attached
are the mailbox (1 message only), logs, sniffed session, testcase and core
dump backtrace. If the dovecot.conf is needed, just ask (it's pretty much
the default configuration).

Maybe this has just been fixed in -test28, in which case you can just
delete this email. :)

Btw, it's rather irrelevant, but does anybody know a good way to read the
qmail alias user's mailbox remotely (imap? The only way seems by assigning
a password to the account...


Regards,

  wouter
