No routing to vpn network takes place if option "use only for resources on this network" is checked for gateway.

[Quax Eros]

This happenes since update of 04-21-2012 (on kubuntu 11.10)

The VPN connection was pre-existing and working.fine.Gateway option "use only for resources on this network" is checked in the routing tab.
(if i uncheck it, VPN gateway becomes the default and routing is proper.)

Since update no routing seems to take place to the vpn-connected network. ping and traceroute go straight to public dns to look for a route which is ofcourse not found.
