Because I work on networking software, I am not online 24/7 and do not
always respond to email every day.  If I'm in the middle of fixing up
some large changes or (in this case, debugging dbus permissions issues
with VPN plugins that requires a lot or rebuild/reboot cycles) I may not
check email until later in the day, and then other mails might require
faster replies.  I do not channel work email to a Blackberry.  Chill
out.

The error about supplicant manager state is not important, as the
supplicant later transitions to idle/ready state and NM proceeds.  What
*is* important is the inability of the driver to perform scans, which
means that no scan list is available for the supplicant to work with,
and thus it cannot associate with any known AP.  What we want now is
driver debugging information about *why* the driver refuses to perform
scans.
