Bone Heat Weighting is not a guaranteed process, it can fail in some cases… We already have a report about it, will merge this one in.

Actually, with 2.70 it is a guaranteed process. Since 2.75 it doesn't work at all. And that is only with a Rigify generated rig.
Most Rigify Video Tutorials including payed once are even based on that process.

It's not just some bones failing but all of them.
