Comment 2 for bug 459998

From davfs2.conf manpage:
              An ordinary user is not allowed to mount within the home direc‐
              tory of another user. But sometimes system users (like nobody)
              get assigned home directories (like /), that include common
              mount points. This option allows to give a comma seperated list
              of system users that will be excluded from this check.
              Only allowed in the system wide configuration file.

So, the following line to /etc/davfs2/davfs2.conf should solve the problem without disabling the oops tracker:

ignore_home kernoops
