Description Rani Ahmad CLA 2014-12-18 11:19:04 EST 
This is a copy-paste of the bug I have. i get it upon Auto Completion when I press Ctrl+Space to give me the context menu of any class members.

I am asked to disable the Template Proposal to stop the error message from re-appearing. I cannot type . on every keypress I get the same error. this is confirmed.
