Steps to duplicate:
Login to SUSE Studio
Click on an appliance to edit it.

I get an HTTP 500, and while the error is nice and customized, it's
ultimately not helpful. Happening for a couple of hours now. It started
while I was in the middle of building my appliance (the last of a couple
times as I was actively working on an appliance).

I've tried refreshing, logging out and in, etc.

Good luck.
