please see my comment here: https://bugs.edge.launchpad.net/ubuntu/+source/network-manager-applet/+bug/436242/comments/2

I think i fixed this in bzr. we kicked off a new build in our daily archive: https://edge.launchpad.net/~network-manager/+archive/trunk ... should be available in a few hours.

Thanks. that confirms what I thought.

So, I just had an apport crash report. It had the same title as this bug, although reading the comments I'm not sure if it's the same problem. I clicked "it's my bug too" anyway. But should I have done that, or should I have sent in my full stack trace anyway and let you dupe it if indeed it is a dupe?

I have debugging symbols for the GNOME stack on board, which means apport uploads are not small, and it's a shame to waste all this bandwidth if dupes aren't going to use the data.

Suggestions welcome.

This bug was fixed in the package network-manager-applet - 0.8~a~git.20090923t220421.1ac8ffd-0ubuntu4

---------------
network-manager-applet (0.8~a~git.20090923t220421.1ac8ffd-0ubuntu4) karmic; urgency=low

  * LP: #436061 - fix nm-applet crash when no APs in proximity; drop assert on a GList, which
    explicitly can be NULL.
    - update debian/patches/nm08-applet-preview.patch
  * LP: #436179 - nm-applet assert failure: ERROR:applet.c:481:applet_menu_item_favorize_helper:
    assertion failed: (favoritePixbuf); simply return with warning if favorize helper is invoked
    without a favorite pixbuf
    - update debian/patches/nm08-applet-preview.patch
  * important UI tweaks for karmic beta: 1. don't use an icon to indicate favorites/known
    connections - the heart was just too ugly; 2. dont put "Active" separator above the
    current active connection; in turn we make the current AP bold; 3. increase xpadding for
    title items (e.g. Wireless Networks) to 10.0; 4. do not visualize all visible connections
    as active if a device is disconnected.
    - update debian/patches/nm08-applet-preview.patch
