Build #1582 appears to have failed because both tests/image.py and tests/mask.py write foo.fits. The temporary files written by tests should have unique filenames.
afw tests use the same name for a dummy file: test.fits
Any objections to me closing this as Won't Fix? It's already been marked as a duplicate of DM-1439, and that's been completed.
Hang off until we have a "duplicate" status on Jira?
Will do - Robert just pointed me at the HipChat discussion that suggests that one is coming soon.
I'm not sure that waiting for a "duplicate" status is really necessary – I dunno if one is coming any time soon, and, even if it is, I'm not sure it's really any clearer than "Won't Fix; duplicates ...".
