View Source, Switch Branch, Broken Link

Hey Team!

I've found a bug where I get a 404 Error page after switching between branches in the Source view area. Here are the steps that I've taken to recreate the bug;

1. View the repo (https://bitbucket.org/ghagivassilis/test-run).
2. Select "Source" from the menu.
3. From the 'master' branch, switch to another branch ('creative' in my repo) using the branch selection drop-down.
4. Open a directory within the new branch ('Creative' in my repo).
5. Switch back to the 'master' branch using the branch selection drop-down.
6. 404 Error Page.

I hope this helps, if you have any questions or require me to do some further testing please let me know.

George.
