A bit more:

[root@tlondon ~]# cat /usr/share/GConf/gsettings/org.gnome.seahorse.recipients.convert
[org.gnome.seahorse.recipients]
show-validity = /apps/seahorse/listing/show_validity
show-expiry = /apps/seahorse/listing/show_expires
show-trust = /apps/seahorse/listing/show_trust
show-type = /apps/seahorse/listing/show_type
sort-by = /apps/seahorse/listing/sort_by[root@tlondon ~]#

I have fixed this by uninstalling and installing seahorse. Now it works for me (no more segfaults)

After rebooting, I have seen the segfaults again. The only workaround is uninstalling seahorse completely

Looks like this has been fixed in seahorse by now; there is no file named org.gnome.seahorse.recipients.convert anymore, and the existing conversion files work fine here.
