Firefox sin el gnome window decorator

Gente,

Luego de hacer el upgrade a intrepid, firefox perdió el windows decorator,
la barra donde están las opciones de maximizar, minimizar ,etc.

Desactive algunos addons que creí que pudieran estar causando el problema y
esto lo solucionó hasta que me volvió a pasar dias despues sin haberle
instalado nada a firefox.
Borré el ~/.mozilla reinicié y de nuevo parece que se corrigió el problema,
me gustaría saber si han experimentado algún problema similar. Revisando
logs de metacity encontré esto:
