Error when trying to view a log

[nwgh]

Entered a log so I could try to track down the source of a bug. Parsing got something like 99.9% of the way there, and then the progress bar just stopped, and I was never able to do anything with the log. The log was created from startup using the appropriate environment variables (not about:networking). The URL that was loaded was from bug 1397621, and loading was cancelled by hitting escape. The browser was then cleanly shut down. The problematic log (from a fresh profile, so no PII) is
moz.log.busted.gz

The following error was in the devtools console:

Safari words it as (not sure if this will be helpful):
