NetworkManager randomly dying?

[Wes Shull <wes kuoi asui uidaho edu>]

Has anyone else observed NetworkManager dying on them randomly?  I say 
randomly because I don't see a pattern to it yet; no doubt it is 
deterministic in some way.

I'm current on rawhide, including NetworkManager-0.2-1.

Nothing spectacular happens to indicate its death; I just happen to 
occasionally notice the network is down, and...

# service NetworkManager status
NetworkManager dead but pid file exists

The only remotely useful thing I can find in /var/log/messages:

Aug 31 00:00:22 ip68-110-7-34 NetworkManager: AUTO: Best wired device = 
(null)
Aug 31 00:00:22 ip68-110-7-34 NetworkManager: AUTO: Best wireless device = 
(null)  (null)
Aug 31 00:00:22 ip68-110-7-34 NetworkManager: 
nm_state_modification_monitor(): beginning activation for device '(null)'

with this additional line after those in /var/log/debug (to which I have 
syslog dumping *.debug):
Aug 31 00:00:22 ip68-110-7-34 NetworkManager: 
nm_device_activation_cancel(eth1): canceled

I'm planning on doing further debugging, but first maybe someone needs to 
add the NetworkManager package to bugzilla?  Or is it there and I'm just 
blind?
