Uploaded files are getting C:\fakepath\ prepended to them (BB-1432)

See:

https://bitbucket.org/tortoisehg/thg-winbuild/downloads

Just started happening in the last day or two. It did not happen when I uploaded files to https://bitbucket.org/tortoisehg/stable/downloads.

I always upload to thg-winbuild with Chrome+Win7. The machine that uploaded to stable was Firefox+Vista, if that matters..
