Hi, I just ran strace on maildrop and it doesn't seem to include any kind of fcntl*(*, F_SETLKW, *) call on the potato+sid machine. It seems I can reproduce the bug on my sid machine too now, but it _does_ do the fcntl() lock on it, yet mutt still bitches.
Downgrading maildrop to 0.75-2 makes mutt say "New mail in this mailbox." like before. I've done a diff between strace logs from both versions and noticed only two differences: -open("mail/spam", O_WRONLY|O_CREAT, 0660) = 3 +umask(077) = 07 +open("mail/spam", O_WRONLY|O_CREAT, 0666) = 3 +umask(07) = 077 I don't actually think this stuff should affect anything since that file already exists, i.e. it won't be created again using the the mask&~umask. Then again I'll refrain from further comments on this since I don't actually know how it works :) Any help appreciated. -- 2. That which causes joy or happiness.
