I'm currently reading the following error in my js console:

Uncaught InvalidCharacterError: Failed to execute 'add' on 'DOMTokenList': The token provided ('an unknown os' contains HTML space characters, which are not valid in tokens.

The nasty side effect of this is that many of the functionalities of the bitbucket site are currently not working for me because they rely heavily on javascript.

OS : FreeBSD 10.2

Browser : chromium-45.0.2454.101
