When requesting the control panel I get the following error:
Fatal error: Call to a member function getTimeFormat() on a non-object in /craft/app/etc/requirements/RequirementsChecker.php on line 103
craft()->locale is null, but I have no idea why this is the case. I'm running craft locally, on http://[PROJECT].craft.dev/ and installed the Pro version.
Edit: this turned out to be a too restrictive gitignore file, ignoring the craft/app/framework/i18n/data folder
