I was playing around with dovecot-1.1 and maildir++ quotas, and ran into a reproducible error with indexing. This only seems to be a problem for new maildirs. If I send a message without the quota plugin on, and "seed" the index/control files, future deliveries with the quota plugin seem to succeed without errors.

Here's the deliver-log from a "fresh" Maildir (just ~/Maildir/{cur,new,tmp}):

Turning off the quota plugin will allow the delivery to succeed:
deliver(example@example.com): Sep 21 18:42:08 Info: auth input: example@example.com deliver(example@example.com): Sep 21 18:42:08 Info: auth input: home=/home/vmail/domains/example.com/example deliver(example@example.com): Sep 21 18:42:08 Info: auth input: uid=1014 deliver(example@example.com): Sep 21 18:42:08 Info: auth input: gid=1014 deliver(example@example.com): Sep 21 18:42:08 Info: maildir: data=/home/vmail/domains/example.com/example/Maildir deliver(example@example.com): Sep 21 18:42:08 Info: maildir++: root=/home/vmail/domains/example.com/example/Maildir, index=, control=, inbox=/home/vmail/domains/example.com/ex ample/Maildir deliver(example@example.com): Sep 21 18:42:08 Info: msgid=<1989.0003.0000@server011>: saved mail to INBOX
Turning quota back on has a temporary complaint about uidvalidity:

But then it's pretty happy:
deliver(example@example.com): Sep 21 18:45:36 Info: Loading modules from directory: /usr/lib/dovecot/modules/lda deliver(example@example.com): Sep 21 18:45:36 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib10_quota_plugin.so deliver(example@example.com): Sep 21 18:45:36 Info: auth input: example@example.com deliver(example@example.com): Sep 21 18:45:36 Info: auth input: home=/home/vmail/domains/example.com/example deliver(example@example.com): Sep 21 18:45:36 Info: auth input: uid=1014 deliver(example@example.com): Sep 21 18:45:36 Info: auth input: gid=1014 deliver(example@example.com): Sep 21 18:45:36 Info: Quota rule: root=mailbox= storage=102400kB messages=0 deliver(example@example.com): Sep 21 18:45:36 Info: maildir: data=/home/vmail/domains/example.com/example/Maildir deliver(example@example.com): Sep 21 18:45:36 Info: maildir++: root=/home/vmail/domains/example.com/example/Maildir, index=, control=, inbox=/home/vmail/domains/example.com/example/Maildir deliver(example@example.com): Sep 21 18:45:36 Info: msgid=<1e42.0003.0000@server011>: saved mail to INBOX
But once I hit the quota limit, I get an assertion failure:
