Here's the problem as I understand it.
I think my passwords are not being saved/restored by whatever agent is supposed
to do this, and this is causing the same kind of symptoms with kmail and with
NM. In both cases, it seems passwords are not available, and some times, kde
doesn't seem to know how to ask for them (for NM, sometimes it pops up a dialog
asking for my wireless pw, but sometimes it doesn't and just stairs at me
dumbly).
