Helm v3 segfaults on helm ls and helm upgrade

It seems as though Helm v3 is crashing in a seg fault when running helm ls, helm upgrade, and possibly other commands. This only happens after a release has been installed into the cluster.

To reproduce, starting with a fresh cluster:

make bootstrap
make build
helm ls    # For sanity - this should work
helm create /tmp/foo
helm install /tmp/foo --generate-name
helm ls    # At this point, it's broken
# The upgrade command fails in a similar fashion
helm upgrade foo-********* /tmp/foo    # Release name has to be grabbed from the helm install command, since it can't be examined with ls

Here's the stacktrace generated by helm ls:

panic: runtime error: invalid memory address or nil pointer dereference

Unit tests are still passing. I'd love to debug this, but I'm not sure how. Let me know if more information is required

e509416 is a little old there. This was fixed in #5455. Can you please check with a more recent version?

oops, forgot to pull upstream 😳

This is resolved.
