[Dovecot] Bug: mbox-sync-parse.c

[John Harper]

I was using rc24, mbox format with indices stored in the mail
directory, which has quotas. Yes, I know I should not do that, but
with 12000 undergrads I can't put anything on another partition
without quotas, else they'll find it....

Usually just the indicies get messed up if a user goes over quota,
which often fix themselves if they log in twice (after getting
under quota again). 

But one student was getting

dovecot: Mar 09 11:27:06 Error: IMAP(02abcdef): file
	mbox-sync-update.c: line 38 7 (mbox_sync_update_header):
	assertion failed: (ctx->mail.uid != 0 || ctx->pseud o)
	
I tried his inbox under rc26, which reported differently:
dovecot: Mar 09 11:53:50 Error: IMAP(00tester): Out of UIDs,
	renumbering them in mbox file
	/windflower/testmail/00tester-tmp/.mail
dovecot: Mar 09 11:53:50 Error: IMAP(00tester): UIDVALIDITY changed
	(1173459229 -> 1042770870) in mbox file
	/windflower/testmail/00tester-tmp/.mail
dovecot: Mar 09 11:53:50 Info: IMAP(00tester): Disconnected: Mailbox
	is in inconsistent state, please relogin.

but logging in again did not help. In the inbox the first message had
an extra header:

X-IMAPbase: 1042770870 4294967294 $MDNSent

which once removed fixed the problem.

Just recording this, in case someone else has a similar issue.
