Reportedly, Idf0a6547 causes insertDefaultSites to fail with an error: "Warning: Invalid argument supplied for foreach() in /Library/WebServer/Documents/wikidata-repo/extensions/Wikibase/lib/includes/Utils.php on line 88" I was not able to reproduce this, but to allow for easier investigation of the issue, I have submitted changes that report more meaningful errors on failure: Iab7e750e for Wikibase and Iad3995a6 for core. If you experience the problem described above, please patch these in and report your findings.
The problem seems to be cause by CRUL not trusting any SSL CA by default on some systems: http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/ We may need a configuration setting to allow people to disable the "HTTPS per default" behavior.
