This is the sort of thing that makes some people really wary of the GPL and other "viral" licenses, and I don't think you can blame them. The "blame" for this falls on someone for throwing in GPL'd code into an MIT project, but the headache drops onto a whole bunch more people down the line. It seems other commenters think this will probably be alright, but I bet this is a lot of corporate type's worst nightmare, that some underling added some segment of GPL code to their product, and now the entire thing is "technically" GPL.
One can only imagine if it was AGPL instead of GPL, and how people would debate if they should send source requests to all the sites running on rails ;-)
