crucible clone fails on large files checkout form mercurial. How to overcome this?

[Vasu Subramani]

This repository uses the largefiles extension. Please enable it in your Mercurial config file.

This is the error crucible throws when trying to clone mercurial repository.

I have enabled large file in mercurial config file. Even after enabling large file extension both on mercurial and crucible server i dont see any progress in crucible.
