[Dovecot] utime : operation not permitted

[Jim Horner]

With the upgrade to 1.0.1, I am seeing some errors/warnings

dovecot: IMAP(jhorner at arinbe.com): utime(/home/arinbe/Maildir/.info/tmp) 
failed: Operation not permitted: 1 Time(s)
dovecot: IMAP(jhorner at arinbe.com): 
utime(/home/arinbe/Maildir/.resumes.vabch/tmp) failed: Operation not 
permitted: 1 Time(s)

Different directories on different days. 
Different users on different days.
Always /tmp directory.
Always a /tmp of a shared namespace.

The /tmp directory in question is mode 770, with group users, just like the 
rest of the /arinbe/Maildir hierarchy.

As far as I can tell it doesn't affect anything on the client side.
