[Pkg-utopia-maintainers] Bug#707177: network-manager: Segfault when enabling wireless or wired connection

[Trey Blancher]

Package: network-manager
Version: 0.9.8.0-4
Severity: important

Dear Maintainer,

   * What led up to the situation?
	 My network connection worked (both wired and
	 wireless) were tested, in an office setting (the wireless was known
	 to work where I was staying). At this office, I upgraded
	 network-manager and firmware-realtek, and still had no problems
	 connecting.  When I got to where I was staying the night, as soon as
	 I brought my laptop out of suspend, NetworkManager tried to connect
	 and then the systray icon disappeared.  I tried starting it again,
	 and it connected to the BLANCHER-Guest network, rather than the
	 BLANCHER network.  When I changed it to BLANCHER, the animation
	 seemed to indicate that it was almost connected, then the icon would
	 disappear.  My clue that it was a segfault came from dmesg:

		[ 7814.774882] NetworkManager[17068]: segfault at 8 ip 0000000000484b39
		sp 00007fffa6232da0 error 4 in NetworkManager[400000+fb000]

	 This message appears every time I try to start NetworkManager, and it
	 crashes every time.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
		 I tried rebooting, but the segfault message in dmesg did not give
		 me hope that it would work.  I also upgraded my kernel from
		 linux-image-3.2.0-1-amd64 to linux-image-3.2.0-4-amd64, thinking
		 there might be an incompatibility in the non-free firmware.

   * What was the outcome of this action?
		 Neither of these things worked.  To workaround the problem (and
		 restore my Internet connection), I manually configured a wired
		 connection, and installed and loaded wicd and wicd-gtk.  I then
		 removed the manual /etc/network/interfaces connection I had made
		 for eth0.

   * What outcome did you expect instead?
		I expected NetworkManager to bring up my wireless connection, and
		not crash.

		I installed network-manager-dbg hopefully to make it easier to debug
		I am attaching a set of strace output run against NetworkManager
		(run as root).  When NetworkManager segfaulted, strace did not
		return, so I had to SIGKILL it.  Let me know if there's a better way
		to capture this info.  I'm also including a syslog excerpt which
		shows NetworkManager, wpa_supplicant, and dhclient messages in case
		they are useful.

		Since wicd works, I'm not inclined to believe it's the wireless or
		wired drivers, or wpa_supplicant, or any other piece of software
		than network-manager.
