gnome-keyring-daemon backtrace

Description of problem:
Occasionally, when I am trying to connect to a WPA2 wireless network with nm-applet, the icon will suddenly stop animating.  I ran pstack and saw that nm-applet is waiting for a reply from gnome-keyring-daemon, which is hung waiting for a mutex.

I'm experiencing a separate issue in which attempts to connect to the network time out and nm-applet presents the "Wireless Network Authentication Required" dialog, even though the password was correct the first time.  The gnome-keyring hang seems to be triggered just before that dialog would open.  To reproduce the gnome-keyring problem on a machine not affected by the network problem, it might be necessary to enter a deliberately wrong password.

Version-Release number of selected component (if applicable):
gnome-keyring-2.28.2-2.fc12.x86_64

How reproducible:
Sometimes

Steps to Reproduce:
1. In nm-applet, select a WPA2 network for which the password has already been saved in the keyring.
  
Actual results:
nm-applet blocks waiting for a response from the hung gnome-keyring-daemon.

Expected results:
No hang, nm-applet continues to operate normally.
