Status in "network-manager-pptp" source package in Ubuntu: Confirmed

Bug description:
Binary package hint: network-manager-pptp

Package version: 0.7~~svn20080818t061112-0ubuntu1~nm1~hardy1
uname -a: Linux jim-d620 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686 GNU/Linux

I am testing the SVN version of network-manager 0.7. I am attempting to connect to my employer's Windows PPTP VPN. Each time I try, the connection fails, displaying a pop-up message that says: The VPN connection 'Connection Name' failed because the VPN service stopped unexpectedly.

The relevant section of /var/log/syslog is:

My internet connection is via a Sierra AC 595 PCMCIA aircard, which is managed by Network Manager and seems to work fine. The VPN connection worked using wired and wireless connections and NM 0.6.6. I switched to 0.7 because I couldn't use the VPN with the aircard under 0.6.6, I think because of this bug: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/145107
