Ralf, this is quite old bug, fixed by commit 9f0d793b52eb2266359661369ef6303838904855.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=9f0d793b52eb2266359661369ef6303838904855

It should be in 2.6.31.y somewhere too, and fixed in 2.6.32.

I hit it with dovecot too.  It should be in redhat bugzilla too.
