NPE when using filter

[Cobra]

What steps will reproduce the problem?

1. set a filter (e.g. "highway:", inverted, do not hide the filtered elements)
2. move the cursor over a node of a non-filtered way (e.g. highway=residential), causing it to be highlighted
3. trigger a redraw (either by the initial highlight or by doing anything else including switching windows)

What is the expected result?
obviously nothing except for the highlighting

What happens instead?
Tthis error. again and again. josm is rather unusable.

Please provide any additional information below. Attach a screenshot if
possible.
This seems to depend on freshly downloaded/opened data. Deactivating and reactiving the filter after this error occurred won't trigger it again.

I'm rating this as major, since it makes josm quite unusable but saving and uploading is still possible when suppressing further errors of this type.

[akks]

I was able to reproduce it only when using Ctrl-Alt-E to turn filter on/off.

In 5074/josm:

Fix NPE for disabled image loading, see #7498, #7491 (please check!)

[akks]

seem to be fixed.
