FirebaseMessaging can't open database, probably because of "Data Protection" capability.

[READ] Step 1: Are you in the right place?

Yes, we have a lot of crashes in Fabric now

[REQUIRED] Step 2: Describe your environment

• Xcode version: 9.0.1
• Firebase SDK version: 4.3.0
• Firebase Component: Messaging
• Component version: 4.3.0

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

We have just upgraded Firebase SDK in our app from version 3.9.0 to 4.3.0 and now seeing a lot of crashes in fabric. Below is crash report:

The crash might be related to #199

Relevant Code:

We just upgrade the Firebase SDK from 3.9.0 to 4.3.0.
We have 3 targets in the workspace which basically have the same code base (and the same version of Firebase SDK). From these 3 targets we build 3 apps targeting different countries.
2 of the 3 targets (says target A and B) don't have such above crash.
Only 1 target (says target C) has currently about 1.1 million such above crashes in Fabric.

The difference of target C to target A & B is that it uses CoreLocation for background location tracking. All of our targets have also "Data Protection" Capability enabled. We suspect that the app is awaken in the background and because of "Data Protection", firebase can't open/create the database in the desired place.

[paulb777]

Thanks for the report and letting us know about the correlation with "Data Protection". We'll investigate.

Investigators, see #199 and #265

[antranapp]

Just some more information related to this issue.

We've just released a new app version including firebase 4.4.0 version, which still doesn't contain the above pull request. For some reason the crash disappeared. I didn't fix anything in the app related to this firebase issue. We just upgrade firebase hoping that the issue will go away. It did !!!!!

So I assume that something is corrupted in firebase 4.3.0 binary build.

Closing, as this hasn't seen new reports. If this resurfaces please reopen the issue.
