Divide by zero error while viewing geotagged image

[ToeBee]

What steps will reproduce the problem?

I have been going through some GoPro images, preparing them for upload to Mapillary/Kartaview. I deleted some images where I wasn't moving (which explains the file not found errors in the logs) but then I was viewing the next image in the sequence. I am using a touchpad on a laptop so I'm not sure *exactly* what I was doing at the time that the divide by zero happened. I think I had zoomed all the way in by clicking and dragging in the image and was then trying to zoom back out using two finger scrolling on the touchpad.

I will attach both a screenshot of JOSM and the image I was viewing at the time.

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

Similar to #22610?

It does seem similar. Interestingly, JOSM did not crash for me. I was able to continue using it without further incident after I submitted this ticket.

Closed as duplicate of #22610.

If you can reproduce please add a description to #22610.

A guess is that this requires a race condition, i.e. doing two actions in parallel with a special timing.

Hard to reproduce. Knowing the exact actions would help, even if the timing is hardly reproducible.
