The translation markup for the info box seems to have been lost somehow. I guess it should have been something like
< /translate>{{Info|< translate>< !--T:26--> Curious about [http://www.fsf.org/about/what-is-free-software Free Software]? Read more about it on the Free Software Foundation's [http://www.fsf.org website].< /translate>}}
The markup must have been in place at some point, because the translation system has a unit 26 with the indicated content.
