Loading UI immediately causes panic: runtime error

[moertel]

Starting the image works fine. However, as soon as I visit the site in the browser, the following stack trace appears in the logs (while the UI remains stuck at "Loading image spies for the first time..."):

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x38 pc=0x65baaf]

The only odd thing about some of our (private) images might be that they may contain additional / characters in them, e.g. an image name might be our-registry-server.com/path/to/someimage:latest.
