In analyzing the backtrace, the regression may have been introduced by patch [1] to fix bug 1407046. [1] https://hg.mozilla.org/mozilla-central/rev?node=2c647187c1a2

I did the other file URI patch, so I'll take this one as well.

It seems like my changes from bug 1450449, which were intended to prevent this very problem, got lost during the refactoring for bug 1407046.

Can reproduce this crash and Bug 1476754(alternatively) by updating Nightly 2018-07-17 to the 07/18 build. Cannot install the update on these devices: Google Pixel (Android 9) Samsung Galaxy S8 (Android 8.0) Doesn't reproduce on these lower Android versions: HTC Desire 820 (Android 6.0.1) Nokia 6 (Android 7.1.1)

Also, STR similar to Bug 1476606. It looks like the blank pop-up described there it's the Nightly crash reporter, which can be seen better on a Samsung S8: https://www.screencast.com/t/vHHs2Hiwe.

No more crashes on build updates. Also, the pop-up crash reporter doesn't appear anymore. Marking this as fixed. Google Pixel (Android 9) Samsung Galaxy S8 (Android 8.0)
