Describe your problem, including steps to reproduce it

Right clicking any inventory with a heatframe seems to cause a stacktrace: https://gist.github.com/pharaun/4d2b906d18c46e7a4f4feb29aca04a88

Confirmed. Looks like an easy fix though.

Fixed in build 213+ from http://jenkins.k-4u.nl/job/PneumaticCraft-Repressurized/

Will be in the 0.6.8 bugfix release out fairly soon

Fixed in 0.6.8 release

This is confirmed to work, thank you :)
