The colon is a valid piece of shell syntax

    chris pyramid:~$ help :

        Null command.

        No effect; the command does nothing.

        Exit Status:
        Always succeeds.

So you likely want to escape that or put it in quotes or something.

We talked this over on IRC, but for the record:

When used with the quotes and called through ${CMD}, the quotes were passed to gconftool-2 and ended up (translated to &quot;) in the final .xml.

I changed the line for a proper command substitution:

but even then the quotes stay as explained by 'man bash':
When using the $(command) form, all characters between the parentheses make up the command; none are treated specially.

So we should be safe with $($CMD). Famous last words.
