When trying to start the script with Shift+w I get the following error.

Should be working now, see 9bbae70. I wonder how that didn't cause an error for me...

Works fine now, thanks! Was it changed upstream recently, or has it always required three arguments?

[ekisu]

It always required three arguments (git blame on defaults.lua says observe_property wasn't touched in the last 4 years), I just forgot it, and it, somehow, "worked" without crashes for me.
