Are you sure this is the correct syntax? I would expect that you
should specify the mountpoint (target directory) rather than the
source of the mount. eg. mount /home/ingo/leo.Bilder
Do using that still give you the same problem?
Might also be useful to have a log of what strace tells you about
running the command.

(Well, it's not a security issue unless you hand out root access yourself
to untrusted people.)
