disconnects because of "assertion `dev != NULL' failed"


I'm using NM/nm-applet 0.6.6 and I'm very frequently encountering the
problem, that when I manually activate a connection via nm-applet,
(wireless, wpa secured connection) right after it has established the
 connection, it is dropped again. NM logs a message like this:

[network selected in nm-applet, NM establishing the connection]

[Connection is dropped again]

If I try again, NM usually manages to successfully establish a connection
on the seconnd attempt.
Is this a known problem? Any advice how I can get this fixed/debugged?

This problem is very annoying so I'd be thankfull for every help.


Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
