0.9.8 secret agent crash from IRC


This part of the logs shows the problem:

are required.

*** here, get_agent_request_secrets() shuold have called
nm_secret_agent_get_secrets(), which should have asked nm-applet for
secrets.  This does mean the NMSecretAgent now has two in-progress
secrets requests, one for 802.1x on em1, and another for WiFi/802.1x on

NetworkManager[13479]: <debug> [1378226579.475356] [nm-agent-manager.c:120] remove_agent(): 
(:1.575/org.freedesktop.nm-applet/1000) agent unregistered

*** applet quit, so NM should remove the applet as the current agent
from both in-progress secrets requests.  This triggers remove_agent()
which should remove the agent from both in-progress secrets requests.

NetworkManager[13479]: dbus_g_proxy_cancel_call: assertion `!DBUS_G_PROXY_DESTROYED (proxy)' failed
NetworkManager[13479]: dbus_g_proxy_begin_call: assertion `!DBUS_G_PROXY_DESTROYED (proxy)' failed

*** this is likely because the applet's D-Bus connection was closed, and
the dbus-glib DBusGProxy object got a "destroyed" signal from D-Bus, and
NM 0.9.8 doesn't have the fixes to avoid this error message.  These two
messages should be coming from nm_secret_agent_cancel_secrets().  The
fix for this would be to attach to the "destroyed" signal of the agent's
DBusGProxy and then maybe set a priv->destroyed variable in
NMSecretAgent, and then not call these two functions in
nm_secret_agent_cancel_secrets() if priv->destroyed == TRUE.

NetworkManager[13479]: <debug> [1378226579.475425] [nm-agent-manager.c:619] request_remove_agent(): 
(:1.575/org.freedesktop.nm-applet/1000) current agent removed from secrets request 0x7fa1d4b3f4c0/802-1x

*** Notice how we only get *one* removal print here, when there should
be two of them; one for em1's connection and one for wlan0's.  Maybe
instrument remove_agent() with some additional debugging and see how
many secrets requests it actually does remove the agent from?

*** Here when nm-applet registers again it gets re-added to wlan0's
secrets request, but it's actually already there, so the previous
request hasn't been cleaned up at all.
