Public bug reported:
Binary package hint: network-manager-gnome
After upgrading to nm-applet 0.6.5, nm-applet would segfault upon trying
to retrieve the passphrase for my network.
(Ok, not a released Ubuntu package, but pre-empting the release a tiny
bit by rolling my own from a vanilla gnome-network-monitor tarball and
the ./debian dir from the old network-manager (modified))
Crash is:
Starting program: /home/pcjc2/source/nm-applet-0.6.5/src/nm-applet --sm-disable
Failed to read a valid object file image from memory.

Patch is attached which fixed the issue for me - I just had to re-enter
the passphrase afterwards, and all was ok.
It seems like gnome-keyring didn't find any matching keys (when network-manager
expected to find one for a network it already knew).
nm-applet gets passed a GNOME_KEYRING_RESULT_OK status, as there is no error
per-se (I think), but a NULL (empty) glist. It then proceeds
to use that glist without checking its length.
Reverting the patch, nm-applet doesn't crash again (presumably as it now
finds the key which the patched version successfully stored)
Quitting nm-applet, deleting the key in gnome-keyring-manager and
reloading nm-applet causes the crash to recur.
Probably ought to get pushed upstream - but I'm keen that Ubuntu gets a
heads-up on this since there have already been issues with the
network-manager-gnome binary being dropped out of network-manager.
