Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status.
As a workaround, for now you should be able to set "mtu 1430" in /etc/ppp/options, which should be taken into account when you connect (but it will affect all ppp connections, including VPN).
