614320 - browser_pageInfo.js triggers 2 strict warnings and 1 exception

Status: NEW

(Firefox :: Page Info Window, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

The test browser_pageInfo.js triggers the assertion:

^G###!!! ASSERTION: XPConnect is being called on a scope without a 'Components' property!  (stack follows): 'Error', file /builds/slave/tryserver-linux-debug/build/js/src/xpconnect/src/xpcwrappednativescope.cpp, line 781

which seems to be the fault of the actual page info code rather than the test.  In particular, the assertion is being triggered when we try to call the function:

callee fun: <function doGrab at 0xaf45fc08 (JSFunction at 0xaf415460)>
file chrome://browser/content/pageinfo/pageInfo.js line 513


Are the timeouts in the pageInfo code continuing past when the document is no longer loaded?

Er, sorry, that's the *calling* function.  So I think we're trying to call iterator.nextNode() through a proxy.  Or something like that.

The assertion doesn't occur (anymore), but:
{
