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.
