I also just learned this does not happens always, it happens always FOR
MY USER. I tried with an user I have for a friend, and it only crashed
after a long time. Still, random icons and characters where not rendered
(I see a white skuare in the place of the icon).
I think in my user configuration there is some startup app that makes
the crash happen (I bet it is empathy, since the crash always happens
before the empathy window is shown).
Best regards,
Manolinux.
