The "\" is needed because otherwise the shell would expand any filenames 
which match the wildcard pattern "libtotem-plparse*" in your current 
directory. If there is no such file, it isn't needed. However if there is 
such a file, you will not get the expected result. As an alternative you 
could use quotes.

You can avoid the error messages like this:

find / -name libtotem-plparse\* 2>/dev/null

Granted, if you really have to search in every directory, sudo may be 
necessary. But nearly every file installed from Ubuntu packages are in 
world readable directories.

The risk is damaging your system because find is a possibly dangerous 
command (e.g. with the -delete option), especially if you get the syntax
