CI is passing successfully, bors is cancelling due to the crash.

bors toml:

delete_merged_branches = true

pr_status = [
    "license/cla",
]

status = [
    "Travis CI - Branch",
]

Is this a permissions issue? (If so, bors should say something; it definitely has comment permissions.)

It succeeded after tweaking the protections so I’ll assume it was a permissions issue.

This is interesting, I think I now have a rough idea on what is happening. Will take a look later
