wpasupplicant 0.6.10-2 is working fine over here, furthermore it's in 
testing since march 11th without similar bugs or - as Debian is 
approaching the freeze - major changes in the accompanying package
ecosystem, therefore I downgrade this bugreport to "normal" severity.

This information might give a networkmanager maintainer intial hints, 
unfortunately it's of little help with debugging wpasupplicant if some 
strange GUI beeps or makes funny faces, while essential information about 
the involved wlan hardware (and its kernel modules!) or actual error 
messages are omitted. I'd assume that networkmanager offers an option to 
get slightly more verbose debugging output than 2 unnamed dots not becoming
green, if not there's always wpa_cli and dmesg, which will likely be more 
verbose about the failure condition.

Therefore I'd like to ask for the output of:
- lspci -knn 
- lsusb
[ depending if you're using a PCI- or USB based wlan card ]
- dmesg
- wpa_cli status

Furthermore it would be helpful to know if the affected wlan card can 
operate at all, e.g. by invoking a scan request (iw dev wlan0 scan).

I notice that you're not using pure testing, but rather quite a package mix
between stable and testing, which, at least when it comes to the default 
udev version (158-1) in squeeze, is not compatible to lenny's 2.6.26 
kernel[1] and might be a reason for quite some problems, including 
wireless. Furthermore especially mac80211 based drivers have seen quite some 
bugfixes since kernel 2.6.26, so testing the current default kernel in 
squeeze (>=2.6.32-15) would definately be appreciated. While partial 
upgrades between stable and testing/ following stable are supposed to work,
they're definately less tested than pure incarnations of either, especially 
here dbus communication between wpasupplicant, dbus/hal and networkmanager 
might be affected. While issues like these should be fixed (or at least 
clarified in package dependencies), it's hard to reproduce or pinpoint 
without further information.
