It only occurs on Nexus 5 master. Tim, could you help here?

Comment 5

[Tim Guan-tin Chien [:timdream] (please needinfo)]

I will have to borrow an Nexus 5 to debug this, but first given the fact we have an window on comment 3, it would be faster if we could identify the regressed bug and needinfo the assignee. Thanks!

With Hermes' help，we narrow the Gecko pushlog, please see: http://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=4ed228a6c759&tochange=227d356ac030

Hi David, Hi Ehsan,
Could you have a look at this bug? Thanks.

I am not so sure which patch in the push log results in this issue.
http://hg.mozilla.org/integration/mozilla-inbound/rev/a509c974aa1f (Bug 1162064)
http://hg.mozilla.org/integration/mozilla-inbound/rev/2096212a25cb (Bug 1171486)

[(no longer active)]

This cannot possibly be related to bug 1171486.  If you doubt that, please test by backing out that patch on trunk and rebuilding to see if the issue reproduces.

Comment 9

[Kartikaya Gupta (email:[e-mail])]

The crash in this bug seems to be the same crash I was running into in bug 1142380, and the r+'d patch on that bug fixed it for me. I'll land it as part of this bug, since I suspect it will fix this issue as well.

[Kartikaya Gupta (email:[e-mail])]

Attachment: Patch

Moved over from bug 1142380, carrying botond's r+ from that bug also.

Comment 12

[Kartikaya Gupta (email:[e-mail])]

That being said, this was likely a regression from bug 1162064, and there is likely still an underlying issue that's causing AsyncPanZoomEnabled() to return false when it shouldn't.

Comment 13

[Kartikaya Gupta (email:[e-mail])]

(Likely TabParent::GetWidget() is returning null, which I also saw happening during the keyboard app startup in bug 1125325, and which smaug said should never happen).
