I was initially skeptical of the changes that had been made to this bug (the "crash after theme change" when I am certain that I was not changing the theme, a different upstream product (Epiphany) to the one I was seeing the problem in (Firefox)).
This indicates an icon theme change. That could be triggered by a theme change,
but also by a run of gtk-update-icon-cache (by installing a program or updating
with apt-get), or by installing or uninstalling a theme engine, or by a crash
of gnome-settings-daemon."
My backtrace contains a very similar call so yup, it looks like this is the problem. However I have checked my logs and I case where this happened and no packages had been updated, nor any themes installed. This suggests we in fact have two problems:
1. Firefox can't cope with a theme change after showing the totem plugin.
2. Something is crashing gnome-settings-daemon/spuriously sending out icon cache updates when none have happened.
I have 100% reproducible steps for 1 which I will attach.
