631000 - Crash when logging into Facebook (x86_64)

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Sean Stangl [:sstangl]]

This is consistently reproducible with the 2011-02-02 nightly and a clean profile on Fedora 14 x86_64. The browser must be 64-bit. Ubuntu users do not appear to be able to reproduce, but this may also be a function of differences in the display shown to different Facebook users. (I *should* just be using the default Facebook schema without any customization/apps/etc.)

The 64-bit nightlies have an alarming number of crashes involving a NULL-dereference, but this is the first crash I have been able to consistently reproduce.

Relevant crash report is here (opening this with the nightly crashes it also):

I will debug this when I get back in a few hours.

That stack is a null deref in the guts of glib, if you trust the stack (which I don't; it seems broken to me).

I couldn't reproduce this just now, on a fully updated Fedora 14, with this build:

Sean, can you still reproduce this?

** PRODUCT DRIVERS PLEASE NOTE **

This bug is one of 7 automatically changed from blocking2.0:final+ to blocking2.0:.x during the endgame of Firefox 4 for the following reasons:

 - it was marked as a soft blocking issue without a requirement for beta coverage

I cannot reproduce with the latest nightly. Some system updates also happened in the meantime. Marking WORKSFORME.
