I suspect that means I screwed up the keys when creating the image.

Hi Seth,
looking back do you still bother to keep the report open or should we stick with "I suspect that means I screwed up the keys" and set it to be invalid?

Well lets make that an opt-in, I set invalid now and you can reset if you want.
Greetings cpaelzer

Changed in uvtool (Ubuntu):
status: New → Invalid

Hi Christian,

Well, a stack trace is a poor way to communicate an error as likely as "seeded the wrong key into the image" but there's only a finite amount of time and if this is a low priority (as it looks :) then perhaps 'invalid' is fine.

Thanks
