I keep getting a crash signature of js::Shape::trace(JSTracer*) but there is no explanation of what that is. What does it mean?

I keep getting FF 4 crashing with Win 7 with a signature of js::Shape::trace(JSTracer*). When go to "Search Mozilla Support for Help" it comes back with no answer available. What is it and how can I fix it.

I have checked the minutes of recent meetings at Mozilla, and they have identified the cause of that crash. The minutes state it will be fixed in Firefox 4.0.1

Pending the result of QA testing, Firefox 4.0.1 is due to be shipped on April 26th.

Thanks for the update. I will await the new version.
