Thanks for filing this. We set the path of the Firefox application in some environment variables for the crash reporter to read IIRC; there's plenty of chances to mess it up in cross-platform code so that's probably what's happening. The fact that it doesn't happen on Windows 10 might be due to the improved UTF-8 support on that platform.

Hello! After searching for a manual regression range I found these pushlogs:
Last good build: 750e71a8f79b3b745a6653e555e60acb122f1241
First bad build: e088bb62f286425a30a925fc3355eb40c92f79c1
Pushlog: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=750e71a8f79b3b745a6653e555e60acb122f1241&tochange=e088bb62f286425a30a925fc3355eb40c92f79c1

I don't know for sure that the above pushlog is correct due to the few bugs(and android related) so I'm adding a second wider one containing the changes from 2018-09-14 to 2018-09-15:
https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=28baa3df5f0f530faee1900f43c463f6b77b985c&tochange=5d14d1e9f74d7cac00bdefbda29244d586645682

This changelog contains bug 1490605 with UTF-8 changes so maybe it can be the regressor. If anything else is needed please let me know. Thanks!
