Two users and 11 crashes. Do we need more evidence?

[pocmo]

This crash is only happening on x86 devices. They may have installed an ARM build instead of the x86 build.

We had similar crashes in Fennec and added some code to exit with an error early in those situations.

@pocmo I can see that for local builds, but that wouldn't emit sentry crashes. So it seems like this is actually failing for GPS r-b users? Or perhaps local builds had sentry tokens...

[pocmo]

@grigoryk You mean you see that when installing an ARM build on an x86 device/emulator?

So it seems like this is actually failing for GPS r-b users?

A bunch of users have downloaded and installed builds linked from the README - they may have picked the wrong one.

[jonalmeida]

Removing P1 since this was a user installed x86 build on an arm device, and it's not a valid path for getting the appropriate build.
