[Bug 334122] Re: kubuntu jaunty plasmoid-network-manager can't use mobile broadband

[Wong CS]

Did some digging around and compared the plasma widget configuration
files ($HOME/.kde/share/apps/networkmanagement/connections) and previous
knetworkmanager configuration files
($HOME/.kde/share/config/knetworkmanagerrc).

The only obvious error in /var/log/daemon.log when trying to connect
using my Huawei E220 mobile broadband modem is the following snippet:

--------------------------

Googling for the search term
"nm_system_device_flush_ip4_routes_with_iface: assertion `iface_idx >=
0' failed", I found the following page:
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/289690

The findings in that page seems to indicate that the modem was not
unlocked by NetworkManager using the correct PIN (or any PIN at all). So
that led me to thinking maybe this same error is affecting the plasma
widget.

Looking through my configuration file for my mobile broadband
connection, I noticed that there the parameter for the PIN was defined
in knetworkmanagerrc but was stored in kwallet instead for the plasma
widget.

I'm wondering if it's possible that the plasma widget fails to submit
the PIN information to NetworkManager to unlock the modem leading to
this issue. I know that the maintainer of this package may not have the
resources to test using mobile broadband modems but if this clue leads
to something we'd be much happier for it :)
