Confusingly, the OK one will actually trigger an error message for you, because it tries to do things that are specific to my machines. The not-OK one says "skipping .First", as below, and you'll see why it shouldn't be doing that. Obvioulsy, the files need renaming before you can test them.

Luke Tierney tracked this down and fixed it.  It's actually a fairly old 
bug, but was being masked by another; when he fixed the other one in 
September, this one started to manifest itself.

It should be okay in RC builds newer than r50178 (which should show up 
by tomorrow on most platforms).

Thanks for making this reproducible!
