A bit of weirdness based upon repo name

If I name my repo "chimp", the following URL works fine, and I can drill down into my files.
https://bitbucket.org/castelazc/chimp/src/master/src/monkey/

But if I rename the repo to "monkey", and attempt to use the following URL, I get "Hmm..can't find that one" message.
https://bitbucket.org/castelazc/monkey/src/master/src/monkey/

The only difference in the URLs is the repo name.

This behavior seems a bit off nominal.

Thanks
