Steps to reproduce:
1. Setup wireless network. Type restricted WEP shared password. 
2. Enable autologin (system -> administration -> login window -> security)
3. Shut down computer
4. Shut down wireless network
5. Turn on computer
6. When desktop has loaded open network manager applet menu with left mouse button. (When this bug was reproduced there were three wireless networks available in addtion to the one that was shut down. Computer was not connected to these networks) Keep the menu open like you would wait for the network to come available! With NM-applet menu I mean the quick laucher on the desktop panel. This quick launcer has two computer screens on it when there is no wireless network connected and it shows a blue bar graph when the wireless network is connected.
7. Turn on wireless network and wait until network has booted. 
8. When the NM-applet attempts to access the default keyring gnome (seahorse?) asks for password (allow of deny access to keyring). At this point the whole user interface will freeze. Note at this point you will have the NM-applet menu open and the password dialogue open. Mouse pointed can be moved but nothing can be done.

Other information:
I sincerely do not know if Seahorse is the crashing application since the whole desktop freezez but I believe it is more useful to file this somewhere than nowhere.
