Is this behaviour reproducable?
Can you please test and confirm if 0.8.4 did also show this behaviour.

What's the output of (ifconfig / ifconfig -a) and nm-tool.

It is possible that network-manager gets confused by the tap0 and vde0
intefaces, which it tries to manage and as it doesn't get a connection for them,
it creates an empty resolv.conf.

Could you try adding

[keyfile]
unmanaged-devices=mac:<hwaddr>;mac:<hwaddr>;...

for the MAC addresses of those two interface to
/etc/NetworkManager/NetworkManager.conf and see if that helps.
See also man NetworkManager.conf


Cheers,
Michael
