panic (SIGSEGV) when creating quickstart

Summary

When running jx create quickstart interactively, I'm getting:

[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x2bedf67]

...interestingly this _didn't_ happen when I tried it in batch mode! `jx create quickstart --batch-mode --git-username=markawm --org=markawm --pack=golang-http --filter=golang-http --project-name=mwm-test-8`

### Steps to reproduce the behavior

Run `jx create quickstart` interactively - most options I've tried so far seem to work...

### Expected behavior

No panic.

### Actual behavior

panic.

### Jx version

The output of `jx version` is:
