Hello, When I try to use pyFAI-calib with this

pyFAI-calib --spacing=CH_3.D CH_3.tiff

This is indeed a mis-behavour:
I guess you center clicked which is supposed to remove the last group on point entered, but there were no group of points...

I added a test to prevent this to show up in the future.

Thanks for the report, it is fixed in 3eaec24

This bug has been fixed but in a clean way. I leave it like this until I find a better solution
