Bug#673211: gnome-shell segfaulting

[Daniel Leidert]

Hi,

I've downgraded accountservice and libaccountservice0. Now my sessions
always start in fallback mode. If I then use

gnome-shell --replace

The new shell comes up. I then see such logs/warnings/errors:

Any idea, what's going wrong? I don't have anything useful
in .xsession-errors (except the above) nor my syslog nor daemon.log.
