There is a crontab at this time:

# command to install the new version when you edit this file.
# This file also has a username field, that none of the other crontabs do.

Running scripts of /etc/cron.daily by hand, I found this happens when
/etc/cron.daily/find runs,
and updatedb trigger the crash.
Running updatedb by hand also trigger the crash.
Here are the last syscalls as displayed by strace -f on updatedb :

st_size=1001, ...}) = 0

fsck.reiserfs are fine on every partitions
UPDATE:
A reboot made the problem disappeared, I'll try to find what triggers
it if it shows again.
