Open 1.2.0: Client crashes when placing a signalum-locked Tesseract

[ax1m]

Version:
1.2.0

What is the bug:
Whenever I place a newly crafted private tesseract, I crash to desktop.
From the crashlog it looks like it crashes on trying to set the owner, which is confirmed by the fact that placing a tesseract with the owner already set works fine.

Mod & Version:
Thermal Expansion 4.0.0RC1-119

Can it be repeated:
yes it can, it crashes reliably every single time under the conditions I described

Known Fix:
none

This happens with other Signalum-locked blocks as well. Such as Strongboxes.

Can you set the owner before placing it?

I found a "fix" that worked for me: When placing it (without shift!) against reactor coolant ports it doesn't seem to crash. It doesn't have to be part of a reactor too, so just place one down and then the tesseract.
