Bug Description

Binary package hint: network-manager

Ubuntu Gutsy; I'm trying to connect to a WPA Personal network. I haven't experienced any problems with other networks. Rebooting the system repeatedly sometimes (eventually) works

From the syslog:

I have the same problem with my X40, ipw2100. Manually configuring the interface with network-admin works, after making sure that no wpa_supplicant is running and doing ifdown/ifup.

I am not sure how network-manager should deal with a wpasupplicant that doesn't bring up its socket. Anyway, crashing is definitly not the right answer.
