I have the following line in my GemFile :
gem \'rails\', :git => \'git://github.com/rails/rails.git\'
I get the following error:
It's the issue with the newer version of the Bundler 1.0.14.
I needed to revert to 1.0.13 to make it work. They apparently had some issues dealing with escape characters in Windows.
