1588513 - Crash in [@ java.lang.NullPointerException: at org.mozilla.fenix.browser.BaseBrowserFragment$adjustBackgroundAndNavigate$$inlined$let$lambda$1$1.invokeSuspend(BaseBrowserFragment.kt:5)]

Status: RESOLVED MOVED

(GeckoView :: General, defect)

Description

[Marcia Knous [:marcia]]

This bug is for crash report bp-268ce68d-c8f8-4805-b175-d96c20191012.

Seen while looking at the nightly explosive report: https://bit.ly/2MeQ7xN. This crash started in 10-10 build according to the report, but the build id in Socorro seems to be the same for all devices: 20191004094656.

Although it showed up in Socorro under Fennec, the metadata tab shows it really is Fenix crashing and 71.0a1 version number shouldn't be a version anymore for our fennec nightlies.

Also adding Will to see why this crash may be showing up under Fennec in crash-stats instead of Geckoview.

[Will Kahn-Greene [:willkg] ET needinfo? me]

This crash report has a product id of aa3c5121-dab2-40e2-81ca-7ea25febc110 which is for FennecAndroid, so Socorro rewrites the product name from Fenix to FennecAndroid.

The Fenix product id is eeb82917-e434-4870-8148-5c03d4caa81b.

i've filed a fenix issue for the apparent wrong productid: https://github.com/mozilla-mobile/fenix/issues/6001

There are two other signatures that seem to be similar issues - both showing up in 71 nightly with the same build ID:

• https://mzl.la/2MhlCr3
• https://mzl.la/33uDQuY

[Chris Peterson [:cpeterson]]

I filed a new Fenix issue because this crash is in Fenix code: https://github.com/mozilla-mobile/fenix/issues/6013

• https://mzl.la/2MhlCr3

This stack trace looks like A-C issue: https://github.com/mozilla-mobile/android-components/issues/3827 , which was closed but I will file a new A-C issue.

This crash report has a product id of aa3c5121-dab2-40e2-81ca-7ea25febc110 which is for FennecAndroid, so Socorro rewrites the product name from Fenix to FennecAndroid.

The Fenix product id is eeb82917-e434-4870-8148-5c03d4caa81b.

Looks like the product ID {eeb82917-e434-4870-8148-5c03d4caa81b} is hardcoded.

Is this by design?
