It seems running it in safe-mode fixes it.  Sorry for the false report.

if safe mode fixes it, this is probably caused by an extension, it'd be great if you could try not using safe mode and disable say half of your extensions to see if the problem is still present. if you can find a single extension which is responsible, the problem can eventually be reported to them.

we'd still like a stack trace too btw.

Attached file stack trace from crash
I traced it down to the Walnut theme, and reported it to the theme developer.  Stack trace attached.
My theme (Walnut) only changes the background color of the video control bar from semitransparent grey to fully transparent grey. 
Note, this demo did crash on my machine (WinXP) before, but when I test this with the current build (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081027 Minefield/3.1b2pre) it no longer crashes...
Even if it is something in my theme(s), the browser should never crash on it...

ok, that stack trace isn't helpful.

try installing iceweasel + iceweasel-dbg or something and crashing w/ that.

or use crash reporter....

The crash reporter doesn't seem to be working.  Is there something I can grep/look for in the stack trace to know whether it's 'helpful?'

The standard instructions don't seem to work.

As that report is still being processed, here one that is probably also this video crash:

Ever confirmed: true
Because of bug 456271 we can backout (XBL part of) bug 451037.
Blocks: 451037
Attached patch possible patch (obsolete) — Splinter Review
This way XBL can be used in external docs.
I need to write some testcase.
Attachment #345306 - Flags: superreview?(bzbarsky)
Attachment #345306 - Flags: review?(jonas)
So what's this patch actually doing, and why does it fix this bug?
For some reason (overflow, whatever) scrollbar is attached to the external
document. That document doesn't have object for script handling, so
cloning XBL (in which event handling is current disabled) element to that
doesn't work.
Because bug 456271 protects "non-scriptabable" nodes not to be used in content
scripts, the safety fix for bug 451037 can be backed out.
When you say "external" document do you mean the XBL binding document?

Shouldn't whatever code is involved handle cloning failure?
(In reply to comment #19)
> When you say "external" document do you mean the XBL binding document?
I mean the external svg document which is used to add the effects.
Oh, I see.  But we're cloning from a document with no script handling object (the XBL proto doc) to one without a script handling object (the external resource document).  That should work, no?
That should work, but ClearScriptHandlingObject marks document to have had
a script handling object. So that is why the patch removes those calls.
Can we fix ClearScriptHandlingObject to not do said flagging if there wasn't a script handling object already, in addition to this change?
This backouts Bug 451037.
