Public bug reported:
I'm running Kubuntu Natty. I have a Nokia C5 phone with a Vodafone SIM
installed (in India). Sometimes when I connect this phone it
automatically detects it properly and NetworkManager configures it and
everything. Sometimes, I do not get connected even after repeatedly
trying of physical disconnect and reconnect or software switch off and
switch on of NetworkManager. When I do tail /var/log/syslog, I get:
