@mterry feel free to unassign yourself, but could this be related to dbus "weirdness" you were talking about earlier today, that langasek was fixing?

Michael Terry (mterry) wrote :

No I don't think so. That weirdness manifested as requests to do things over DBus being denied for insufficient permissions. Shouldn't result in crashes.
