README rendering in overview and directory generates incorrect links

See https://bitbucket.org/rstanchak/readme-issue for an example

The REAME.md links to page.md and subdirectory/page.md...

Thus, I expect the links in the overview page to refer to
https://bitbucket.org/rstanchak/readme-issue/page.md\\
and
https://bitbucket.org/rstanchak/readme-issue/subdirectory/page.md

however, the actual links are to
https://bitbucket.org/rstanchak/page.md\\
and
https://bitbucket.org/rstanchak/subdirectory/page.md

The repository component seems to have been truncated.

Viewing the README directly in source view renders the expected urls.
