The intermittent startup Python segmentation issue is related to a 'dbus' 
multi-threading bug, some machines are more prone to it than others (e.g 
quad core CPUs seem to be more prone to it than dual cores). I will be 
releasing a new AccessGrid RPM this week which uses an external single 
threaded program for the Avahi/dbus stuff and should be more stable.

If you want a workaround now, disable Avahi/dbus support in the VenueClient 
by editing:

and change:
     import avahi
     haveAvahi = True
     #import avahi
     #haveAvahi = True
     haveAvahi = False
