assertion in NetworkManager

[Philipp Böhm]

Hello @all,

after upgrading to Fedora 12 I get some problems with NetworkManager for 
example Wireless Networks were disabled and you couldn't avtivate this. 
Some entries in /var/log/messages shows me an assertion in 
NetworkManager. I will post these line and I hope that somebody can help 
me. My wireless-device is an Atheros AR242x 802.11abg Wireless PCI 
Express Adapter (wlan0).

/var/log/messages:
