Mount -o bind strange behaviour

This is the output at the moment.

gremo1:~# mount

No way to provide cat /proc/mount content of /proc/mount before. Mount had the same output and everything seemed to be normal.

This was the mountpoint with the problem. /usr/local/apache/conf on /var/chroot/apache/usr/local/apache/conf type none (ro,bind)
