Running on arch linux and building darktable from master.

I'm not sure when it began but script_manager.lua will no longer start, I see the following error:

LUA ERROR : /home/clu/.config/darktable/lua/tools/script_manager.lua:360: attempt to call a nil value (field 'show')

line 360 is:

script.data.show()

I made sure I am running the latest script_manager.lua from this repo. I'm stumped on the issue.

EDIT:

More specifically, script_manager appears to be loading scripts, but the script_manager module is not visible in the ui.
