When I did the boto -> boto3 rewrite for Socorro, I broke the verify_processed cronrun job. It's failing to run and kicking this error up:

<class 'AttributeError'> AttributeError("'S3' object has no attribute 'get_bucket'")

  File "/app/webapp-django/crashstats/cron/management/commands/cronrun.py", line 147, in _run_one

I think it's this sentry error, but it's really hard to tell since sentry is truncating the message:

https://sentry.prod.mozaws.net/operations/socorro-new-prod/issues/5864397/

This bug covers fixing that.

Grabbing to do now.

willkg merged PR #5057: "bug 1603231: fix verifyprocessed" in 36bb504.

I'll verify this on stage tomorrow.

This was deployed in bug #1603593 just now. Marking as FIXED.
