781004 - DeviceStorage not loading "video" area (gaia video app broken)

Status: RESOLVED DUPLICATE of bug 777259

(Core :: DOM: Device Interfaces, defect)

Description

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

When it loads, there's just a black screen.  In logcat I see

E/nsVolumeService(   77): GetVolumeByPath: Unable to find volume by path: '/sdcard'
E/GeckoConsole(   77): [JavaScript Error: "TypeError: storage is null" {file: "app://video.thisdomaindoesnotexist.org/js/video.js" line: 31}]

I'm making a small test case that I'll attach here in a minute.

Closing the video app and then reopening makes the bug go away.

Attachment: Small gaia test

STR
 (1) cd $b2g/gaia && git apply 781004-test.patch && make install-gaia
 (2) Open "Template" app

See 

E/nsVolumeService(  453): GetVolumeByPath: Unable to find volume by path: '/sdcard'
E/GeckoConsole(  453): [JavaScript Error: "TypeError: storage is null" {file: "app://template.gaiamobile.org/index.html" line: 15}]

in logcat, and the message "BUG!!!" in the UI.

The code in this testing patch is extracted from the video app.

I see the same thing.  Basically, we ask the Volume Manager if the "sdcard" exists.  It says, no.  So, we go ahead and return nothing to web content. 

I can also reproduce this in the gallery.

If I flash the phone using ./flash.sh then I see the problem for the run that occurs immediately after the reboot from flashing. If I do an adb reboot, then it works fine.

After my preliminary debugging, it looks like the Volume Manager is failing to become "Ready". Still investigating...
