1018909 - Homescreen crashes on loop

Status: RESOLVED DUPLICATE of bug 1018406

(Firefox OS Graveyard :: Gaia::Homescreen, defect)

Description

[Dave Hunt [:davehunt] [he/him] ⌚BST]

Attachment: logcat.txt

It appears that immediately after flashing and completing the FTU the homescreen is crashing on a loop.

The last known good build was:
application_buildid: 20140530003925
application_changeset: e6f113c83095
gaia_changeset: 26d8fcab9b61f46451600f39c51e0387ef3c4f88

The issue then first appears in:
application_buildid: 20140530050928
application_changeset: 76432b693fc4
gaia_changeset: 26d8fcab9b61f46451600f39c51e0387ef3c4f88

The issue then appears to be resolved in:
application_buildid: 20140530124652
application_changeset: 50305ee11618
gaia_changeset: e98fe1e94d3d80ad36903500d8ca3333904b162c

And then regresses again in:
application_buildid: 20140530130452
application_changeset: 6f9eb2bb1103
gaia_changeset: e98fe1e94d3d80ad36903500d8ca3333904b162c

It then appears resolved again in:
application_buildid: 20140531031552
application_changeset: 85f6afe5cdde
gaia_changeset: e98fe1e94d3d80ad36903500d8ca3333904b162c

And finally regresses again in:
application_buildid: 20140531162052
application_changeset: fc91e69c3473
gaia_changeset: e98fe1e94d3d80ad36903500d8ca3333904b162c

This was picked up by our automation, which seems to fail when launching applications. The symptoms appear as any of the following, and maybe others:

JavascriptException: TypeError: this.app.element is null
JavascriptException: TypeError: GaiaApps.getActiveApp(...) is undefined

I've attached a logcat showing the initial crashing of the Homescreen app. This is then repeated on a loop once the user completes the FTU.

The regression ranges don't appear to be particularly useful. I am however able to confirm the results manually. Perhaps this is an intermittent build issue? I'm hoping the logcat will prove useful.

I can still reproduce this issue on todays(2014 06 02) flame build :

We can also see this in the Hamachi build:
