Is this definitely from a nightly change, or could a new version of AVG be causing this?

Comment 2

[Benjamin Smedberg]

Nevermind, the crash clearly points to new code added here:

734a282006c2	Trevor Saunders — bug 915558 - save attributes of binding element to the startup cache r=smaug

tbsaunde, we should back this out if there is not an immediate/obvious fix.
