Can you provide the crash ID from about:crashes?
Does it happen in Safe Mode (see http://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode)?

It happens when I run the javascript from the Firebug console. Then after restart it also happens in the Web developer console.
But when I tried just now after a normal restart, the browser didn't crash (or close unexpectedly).

There is nothing in about:crashes.
I checked my preferences, I have turned on the setting about submitting bug reports.

And it also happens in safe-mode.

Can you attach a stack trace (see https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report#Linux)?

Many changes have been done to XRayWrapper.
Does it happen in Nightly (http://nightly.mozilla.org/)?

yes, and I got a report id: bp-97eb663a-3f63-45d2-8ccd-6db032120720

[Boris Zbarsky [:bzbarsky]]

This is totally a workers bug.  The manual DOMJSClass stuff (see bug 742189) in Worker.cpp doesn't actually set up proper hooks for Xrays, so the Xray code crashes on a null deref when it tries to use those hooks.

We could obviously add null-checks in Xrays, but then the code in this bug would just throw (which is admittedly a step up from crashing).  Peter, should we do that?

Handing this over to Peter for investigation and update on what we can do here for this tracked regression.

bp-5a984244-9f82-44eb-8bc0-940962120726

Can reproduce reliably with the following steps:
1. Load addons.mozilla.org
2. Open web console.
3. Load var ww=Worker('sdf');
console.log(ww);

This started while 14 was in Nightly:

Suspected: bug 740069

Comment 12

[Virgil Dicu [:virgil] [QA]]

Reproducible on Windows as well.

Comment 13

[Boris Zbarsky [:bzbarsky]]

Well, yes, of course it's a regression from Paris bindings.  ;)

Comment 14

[Lukas Blakk [:lsblakk] use ?needinfo]

Since this is not a high volume crash (does not appear in Firefox topcrashers) I'm wontfixing for 15 and will continue to track for 16/17 since it's reproducible and a regression.

Please add a comment to all users of sNativePropertyHooks to remove it if it's the last consumer and is going away.
