Comment 1

[Matt Woodrow (:mattwoodrow)]

I can't reproduce this, does it crash consistently for you?

Please try again in Safe Mode, I think it might be addon related.

Comment 2

[Justin Dolske [:Dolske]]

I just hit this:

bp-e0f34493-ce3a-45e0-8197-5b4fe2120703
bp-181059b1-fa1b-4354-9b11-fb87a2120703

The first was from a long browser session, I had been reading http://en.wikipedia.org/wiki/A_Fire_Upon_the_Deep#Zones_of_Thought, clicked the author's name (http://en.wikipedia.org/wiki/Vernor_Vinge), and then relatively quickly clicked back (As I noticed a mention of Usenet on the first page, but the latter page started loading before I could read it).

The second (corrupt) bp report happened seconds after the browser session restored, and I did exactly the same thing.

Comment 3

[Justin Dolske [:Dolske]]

And again, same steps: bp-0a11728a-9e04-462b-b58b-74ae32120703

Can't seem to reproduce with a clean profile, though. Perhaps depends on something else? I've only got a few common addon, or maybe one of the 6 apptabs that are also session-restoring on startup...

Comment 4

[David Burns :automatedtester]

Below is my about:support. With a clean profile I am getting details as in bug 770041 so perhaps its addon related. 

Like :Dolske I get my first crash and then I get an empty stack in the next crash

Comment 5

[Matt Woodrow (:mattwoodrow)]

I *think* this will be fixed by the patch in bug 770041, since it reverts the behaviour of GetParentPresContext/GetRootPresContext.

This should be in tonight's nightly, it was just merged to m-c.

I can't reproduce this now so am closing. If I get it again I will reopen
