Interesting; this also depends on knetworkmanager doing the right thing
when NM asks for the secrets for the VPN.  Any chance you can run
'strace -p <pidof knetworkmanager process>' and then hit connect and
wait for it to fail, then send the strace log?  That may allow us to
figure out what's going on.

It's not a known issue, but the knetworkmanager bits are developed by
the KDE project, so people on this list aren't as familiar with them.
It might also make sense to ask there and see as well.  Until then, the
strace might help us get closer.
