I don't see where the liability could come from. If you are worried about being sued for patent or copyright infringement then it is a non issue if you don't make, use, sell, distribute or import a patented software program or copy that of another's software. Just contributing to its development does not give rise to any liability. However if you accidentally copy a portion of another's software that is not designated as open source, and incorporated it into you own software you are developing then you are looking at a problem. Under patent law they would not likely sue you because there are no damages but if it is federally registered as a copyright then they may come after you for statutory damages and attorney's fees.
