Running also 64-bit Ubuntu 12.04 but do not experience this issue. I am in the same network as the bug reporter, but I guess I have a different network card, mine is:
        *-network
             description: Ethernet interface
             product: 82579LM Gigabit Network Connection
             vendor: Intel Corporation
             physical id: 19
             bus info: pci@0000:00:19.0
             logical name: eth0
             version: 04
             serial: d4:be:d9:53:2d:64
             size: 100Mbit/s
             capacity: 1Gbit/s
             width: 32 bits
             clock: 33MHz
             capabilities: pm msi bus_master cap_list ethernet physical tp 10bt

And as with this it works - maybe the problem is in the driver for the network card (just a wild guess).

Best regards, Martin.

Hi Harry,

This is completely normal. If compiz is not completely gone you need
to cal it using compiz --replace.

In your case it is the network-manager applet only that is gone / has
crashed and not compiz.

However, I don't know which other logs to investigate for further
details on possible reasons, must be somebody else coming over with
further hints, please.

Best regards, Martin.
