As you know it is a general consensus that you can't execute anything that has no exec file permission.
This didn't apply to .desktop files, so it introduced a /security/ breach that raised quite a hype over the intertubes (http://www.geekzone.co.nz/foobar/6229)
So, to avoid that situation, the services (.desktop files) that are in the user-space (that is not the system-wide ones) have to have the x bit set. The dialogue above essentially asks you whether you want to set the execution bit.
p.s. And please stop trying to use journalistic (and troll) hooks like... cheerio!
