specifying specific branch in browsing files for repository under repository group leads to invalid URL and causes 404 error.
When browsing files of repository under repository group, and specifying branch from "Switch to commit" RC leads to invalid URL causes 404 error.
- seems that this problem is found only for repositories under repository group, and NOT for repositories under root (i.e. not member of any repository group).
- specifying revision number works fine even if the repository is under repository group
