[Dovecot] POP3 fails on non-existent inbox

[Kenneth Porter]

Using the latest RPM (dovecot-0.99.10.5) on Fedora Core 2. I connected to 
the server by POP3 for a user who'd not yet received email (ever) so she 
didn't have a spool file in /var/spool/mail, and dovecot was failing on 
login.

I just tested it by removing my own mailbox and see this in maillog:

pop3-login: Login: ken [127.0.0.1]
pop3(ken): stat() failed with mbox file /var/spool/mail/ken: No such file 
or directory
pop3(ken): stat() failed with mbox file /var/spool/mail/ken: No such file 
or directory
pop3: I/O leak: 0x8050c20 (0)
pop3: I/O leak: 0x8084b90 (1)
pop3: Timeout leak: 0x8065d00

>From the client, I enter the USER and PASS command and get:

+OK Logged in.
Connection closed by foreign host.
