Bug 235988

Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Summary
-------

Running Kubuntu 10.04, upgraded from Kubuntu 9.10.

I have a PPTP VPN connection called "Work".  Trying to open it the first time fails
with a complaint about "Missing or invalid VPN password".  (I'm never prompted
for a password.)  Trying to open the connection again causes knetworkmanager to
crash.  It will then crash on all further attempts to connect to "Work".

More Detail
-----------

Reboot machine.
Right click on knetworkmanager icon.
Left click on "Work" connection.
No connection is made: ifconfig shows no ppp0 interface.

daemon.log shows:

I wasn't prompted for a password.

Right click on knetworkmanager icon.
Left click on "Work" connection.
knetworkmanager crashes.

At this point restarting knetworkmanager and clicking on "Work" again causes it to crash again.


The crash can be reproduced every time.
