Bug#627955: network-manager: Network-Manager crashes when starting pptp vpn connection

May 25th, 2011 - 04:40 pm ET by Thomas Angermayer | Report spam
Package: network-manager
Version: 0.8.4.0-1
Severity: important

I've set up an pptp vpn connection with the network-manager running under
gnome. I only entered the name of the connection, the gateway, my username
and password, and the option that everyone can use this connection.

When I click on the network-manager (witn the left mouse key) and select
"VPN Connections" and then the connection, I've set up, the NM-Applet
disappears from the Gnome panel and I've to restart it with

NetworkManager &

After that, the NM-Applet appears again. But when I then try to start the
vpn connection again, the same happened as described before!



The following is put in /var/log/daemon.log:

Which version of network-manager-openvpn do you have installed?

Please install network-manager-dbg and run NetworkManager in gdb to get a
meaningful backtrace.

Thanks,
Michael
