Looks to me like it could be helpful for debugging in some cases.

Thanks, Christian!
Are you able to unblock the workflows?

Apologies - I think I missed this back in March. Thanks for the contribution.

This looks useful, assuming tests pass I will merge.

[corranwebster]

Test failures appear to be due to incompatibilities between Qt5 and the latest Pillow version, which is orthogonal to this PR.

So, do I have an action here?

If you can merge in current main, that should like resolve the issue. I can possibly do it but won't have the spare cycles for at least a week.

I'm being told I already have everything:

% git status
On branch fix-issue-1205
Your branch is up to date with 'origin/fix-issue-1205'.

nothing to commit, working tree clean

% git merge upstream/main
Already up to date.

Thanks. Then it's on me to sort out what's going on with the errors.

Hi, I just got this notification on my own fork of PyFace: https://github.com/capn-freako/pyface/actions/runs/7216126167 <https://github.com/capn-freako/pyface/actions/runs/7216126167> I’m assuming this is related, but not sure what to do about it. Can you get me pointed in the right direction? Thanks, -db
