X crashes with SSID Broadcast turned off

My laptop has Xubuntu 10.10 installed (Ubuntu with XFCE desktop).  With the SSID Broadcast turned off at the router (the Netgear I recently purchased), once logged into the desktop, it (X?) crashes and returns to the login screen.  Before the actual crash occurred each time, the network-manager icon did not appear on the XFCE taskbar.






Once SSID is turned back on and logged in, everything is fine.  Why would having this turned off, cause the desktop to crash, unless there is an obvious issue (bug) in network-manager?  On the surface, it would seem that in order to prevent such a crash, Ubuntu and its variants would require SSID be turned on.


FWIW, the video is recognized as ATi Radeon-based (I know there have been issues with this and Linux).
