This bug seems similar to Bug 1330573. 

It has the same stack trace, and it only occurs after https://hg.mozilla.org/mozilla-central/rev/b105a99a50cf (Bug 1245921).
I tried applying the patch from Bug 1328004, but this time it doesn't fix the issue.

Stack trace below, but there are several other errors, all linked to issues with the inspector being destroyed while loading.
