What you're seeing is simply a manifestation of the fact that TeX  
can't find any hyphenation point in the last word of this line (=  
"sables"); hence it reports an overfull \hbox and leaves this word  
protruding in the margin. From the console output:

If you select the [draft] option to the {article} class, you'll see  
black boxes appearing where overfull \hbox'es are found.

I don't understand why "sables" cannot be hyphenated as it should be,  
namely sa-bles. I checked in the log that French hyphenation is the  
one in effect at that point, and it is indeed. For good measure I  
also selected French hyphenation explicitly for this word, namely:


and it doesn't change a thing. I can only see two explanations:  
either the "s" at the end of "sables" isn't recognized as a plural  
form, and makes "sables" unrecognized to the French hyphenation  
pattern; or the "," immediately following "sables" isn't recognized  
as a word delimiter. I don't know whether there's a switch to  
activate somewhere for the latter.

What you can do in any case: set up the hyphenation point yourself,  
either entering "sables" as "sa\-bles", or adding it to a list of  
hyphenation exceptions in the preamble of your file, namely:


Hope this helps,
