CC me on the bug you file - I'd be very interested to find out what the
cause is. Even if quantum is what's triggering it, it smells like it might
actually be a bug in DBus - something like Quantum ought not to be able
to crash dbus after all !

My money would be on something namespace related, since IIUC, quantum
does some playing around with network namespaces at least ?
