781702 - browser shutdown prints the following warning 11 times: WARNING: NS_ENSURE_TRUE(pusher.Push(aBoundElement)) failed: file /moz/mi/content/xbl/src/nsXBLProtoImplMethod.cpp, line 329

Status: RESOLVED FIXED

(Core :: XBL, defect)

Description

[Luke Wagner [:luke]]

It seems like this warning should either be removed or fixed if it prints 11 times on every browser startup.

Oops, I meant *shutdown*.  This is with an empty profile, tested on Linux and OSX.

This affects the size of mochitest logs, since the warning is fairly lengthy (~120 characters on Linux, ~150 characters on Windows) and the warning is printed thousands of times during tests.

r=me, but I kinda wonder why we're failing to push here!

[Stefan Sitter [:ssitter]]

I get this message a lot in my Thunderbird build (mozilla-central: 07919b62b9cf, comm-central: 2303738b90c3) when working in the UI. It is always preceded by the following message:

> WARNING: NS_ENSURE_SUCCESS(rv, false) failed with result 0x8000FFFF: 
> file .../src/mozilla/content/base/src/nsContentUtils.cpp, line 3014

It seems that nsCxPusher::Push() fails because aCurrentTarget->GetContextForEventHandlers(&rv) fails with NS_ERROR_UNEXPECTED.
