I wanted to use the contrib/geoToolbox script to tweak some GPS settings on some images, but it wasn't working.

Inspecting via ./darktable -d lua showed this error
11.0105 LUA ERROR : /Volumes/EXT-Data/Data/darktable/lua/contrib/geoToolbox.lua:310: attempt to call a number value (local '_')

It seems that the use of

for _,image in ipairs(sel_images) do 

causes a conflict with the function _(msgid)

I changed the 8 instances of

for _,image in ipairs(sel_images) do 

to

for jj,image in ipairs(sel_images) do

This fixed the error I was seeing and let me use the script as required.
