This bug is still available in the latest version of Ubuntu 8.1.
I can successfully enter a valid static network configuration.
After a reboot, the file "/etc/network/interfaces" is empty except for the following lines :
   auto lo
   iface lo inet loopback

Thanks in advance.

Still reproducable in Intrepid.

Steps to reproduce:
1. go to network-manager by right-clicking the network-manager icon
2. click 'edit connections'
3. choose auto eth0 or whatever your wired connection is
4. edit, then go to ip4 setings
5. Change DHCP to manual
6. Enter a fixed ip addres, netmask and gateway.
7. close, check if the ip changed
8. reboot
9. you will see that network-manager reverted the wired connection back to dhcp.

Relevant syslog after reboot.

Relevant syslog after changing dhcp to manual, but before reboot

@Ace: Can you reproduce the bug in Ubuntu 12.04?

[Expired for network-manager (Ubuntu) because there has been no activity for 60 days.]
