It might be the case that the AP's old encryption settings were still in
the scan list; How long was the AP powered off before it came back up
with the new settings?  Can you reproduce the situation and run
'nm-tool' to check what NM thinks the AP's settings are and make sure
that NM reflects what they really are?  If not, it's likely a stale
entry in NM's scan cache.

I'd expect to see the passphrase dialog if you change the passphrase on
the AP and not the security settings; if you switch between WEP and WPA
for example then you might also see that dialog, but NM might also be a
bit confused.
