photo_geotag plugin fails to Write coordinates to image header

[simonmikkelsen-dk]

What steps will reproduce the problem?

1. Open JOSM
2. Install the plugins photo_geotag and and photoadjust
3. Open a set of geotagged images
4. Move 5-6 of the images to a new location.
5. Right click on the layer named Geotagged images
6. Select Write coordinates to image header
7. In the dialog, press OK without changing anything.

What is the expected result?

A dialog shows the status of writing headers to the images headers. Image headers are updated.
This will happen until the error has occured, after which the error will occur every time.

What happens instead?

Noting happens. In the console
java.lang.reflect.InvocationTargetException
is printed, with no extra stacktrace.

When this error happens the error will occur every time. The error may happen on the first attempt to save images or after 2-3 successfull saves.
Only solution is to restart JOSM which will discard all changes to images.

Please provide any additional information below. Attach a screenshot if possible.

Attached are some of the files I am trying to change position of. I only change it 10-30 meters.

@Simon, can you still reproduce this issue with the current versions of JOSM and the plugin? It works for me with the images you provided.
Might have been fixed since #20341.
