Proposed debfix including the upstream fix for this issue.

You can also test the built packages with this fix at http://people.canonical.com/~rsalveti/686320/

Tested on my Panda and I'm now able to use the network with Network Manager (also showing the nm-applet at the panel).

I tested the build in rsalveti's home directory on Natty Alpha 1 and it works properly. No errors in the logs.

This bug was fixed in the package network-manager - 0.8.3+git.20101209t061929.638fb18-0ubuntu1

---------------
network-manager (0.8.3+git.20101209t061929.638fb18-0ubuntu1) natty; urgency=low

  * upstream snapshot 2010-12-09 06:19:29 (GMT)
    + 638fb1878019ac75617b653d13f4970af6e9c970
    - core: correct TIMESTAMP type; fixes potential crash when time() is 32bit
      (LP: #686320)
    - libnm-glib: actually define the "ip-interface" property
    - ifupdown: Correctly mark unmanaged devices (debian #569215)
    - ifupdown: Allow to mark bridge ports as unmanaged (debian #530335)
  * Finish fixing daily builds: explicitly checkout/switch to the branch we're
    interested in before pulling new revisions so that it get properly updated.
    - update debian/rules
  * Revert s390 devices patch, it was applied upstream.
    - remove debian/patches/fix-natty-build.patch
    - update debian/patches/series
  * Add support for the 'hostname' dispatcher action that would previously
    trigger useless "exited with error status 1" messages (but not actually
    break anything). For now it will just exit doing nothing. (LP: #661951)
    - update debian/network-manager-dispatcher.script
