I also took a look myself and it turned out that my maildir, which
contains the LKML messages of the last three months, is the root of the
problem. I can now reproduce the bug, by simply running (e.g.):

cp -al /var/backup/hourly.3/localhost/home/markus/.maildir/lkml/. /var/tmp/debug

where /var is mounted as: "/dev/sda1 on /var type ext4 (rw,noatime,commit=60)"
and /var/backup/hourly.3/localhost/ is a previous backup produced by rsnapshot.
