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.)

#2

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

#3

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

#4

For people using github and encountering this -- if you require license/cla status check in your protected branches setting, you need to uncheck the "Require branches to be up to date before merging" checkbox for this to work.
