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.
