"copy_old_to_new" was checking that the field existed previously, but not that it was non-empty. This doesn't cover every possible scenario, and there are likely other cases of invalid metadata in RGB TIFFs that we may need to handle in the future, but we can deal with it when it comes up.

This test (with its associated fixture) passed without any changes to the ImageRemediate code, but I think it's worth keeping as a regression test.

This method (copy_old_to_new) is called here:
feed/lib/HTFeed/Stage/ImageRemediate.pm
Line 1165 in 6b1f116
copy_old_to_new but I don't know if we've run into that exactly.

These changes look good. I appreciate seeing the different tests that consider various scenarios for image validation.

This ended up being a bit tricky to track down because the error didn't give a useful stack trace, and the culprit is buried in the rather long
convert_tiff_to_jpeg2000method.This was indeed a one-line fix (6b1f116#diff-0d491008f8069f2e647a11563976e76d9a8fd71e522c3efbb3b9384b58b93ae6R175), but getting there was a bit tricky in terms of figuring out exactly what triggered the issue, creating a test fixture, and then actually finding the source of the problem.
It may be worth thinking a bit about what we do with ImageRemediate in the future – in particular if we want to make major changes to this in the future we should do some refactoring and unit testing there first.
6b1f116 is the commit with the actual changes. Some comments inline.
