[Dovecot] quota vs. antispam issue

[Johannes Berg]

Can you help me maybe? I don't see the bug.

QUOTA=maildir QUOTA_RULE='*:storage=100M' MAIL_PLUGINS="antispam quota" MAIL_PLUGIN_DIR=/home/johannes/Projects/dovecot/antispam gdb --args /home/johannes/Projects/dovecot/dovecot-1.1/src/imap/imap

I'll keep digging but I don't see why 

        return quota_check(ctx->transaction, ctx->dest_mail != NULL ?
                           ctx->dest_mail : qt->tmp_mail);

should pass NULL in the second argument.
