This bug is not about afm-system-daemon but about trying to see what caused the problem, but you can't do that when afm-system-daemon is the one crashing at boot.
While installing homescreen wgt I got the following:
Then I decided to reboot the machine (not knowing what to do) which resulted in afm-system-daemon segfaulting. At this moment there's no "easy" way to see what caused as you can no longer login into the system.
Without booting with /bin/bash, mount manually partitions and figure out what caused it (if that is an option).
