Bug#471260: clarifications

[Federico Muciaccia]

I've opened the file with another editor (vim): the file seems to be ok.
I've found that the compiling trouble was for a my error in the copy and
paste.
So now I think that the file has no (visible) problems and saving it has
in some way fixed the duplicate line problem.
Today I upgraded to gedit 2.22.0-1 : let's see if the duplicate line
incoherence persist...
