Description Sam Varshavchik 2011-06-01 12:42:17 UTC 
Created attachment 502246 [details]
nm-dispatcher.action renamed to nm-dispatcher.action.orig, and an strace wrapper slipped into its place

nm-dispatcher.action fails to initialize the dhcp environment variables.

I was investigating why dhcp was failing to initialize the server.

I determined that the environment variables that /etc/NetworkManager/dispatcher.d/11-dhclient was expecting, were completely empty.

Wrapping nm-dispatcher.action with strace, the following was logged:

write(2, "\n(nm-dispatcher.action.orig:4743): GLib-GObject-CRITICAL **: g_value_get_string: assertion `G_VALUE_HOLDS_STRING (value)' failed\n", 129) = 129

I suspect this is what's causing the environment variable initialization to fail. Something that nm-dispatcher.action was receiving over dbus was triggering this exception.

strace attached.
