Dive is crashing when browsing layers of paketobuildpacks/run:base-cnb image

[asaintsever]

Using dive 0.10.0

How to repro issue:

• pull paketobuildpacks/run:base-cnb image
• dive <paketobuildpacks/run:base-cnb image id>
• scroll down the layers, dive will end up crashing (see Golang crash dump below)

That should be solved by #395, could you give it a try?
