"commit" crashes the camera calibrator

[rursprung]

it seems that in the camera calibrator the "commit" button is broken: when i do a calibration and click "calibrate", then "save" these two work. if i follow that with "commit" it crashes every time:

tested on ROS jazzy with a local copy of this repo in my ROS workspace with 5.0.5 + a cherry-pick of my fix #1046 (i.e. for the bug reported here it's identical to 5.0.5).
