First, this bug is a regression against 12.10. Booting from a 12.10 live CD I can use the mobile broadband.
The modem is built-in (Ericsson Business Mobile Networks BV).
Id did not get the crash this time, but no connection. According to syslog, modem-manager is trying something infinitely.
I have switched to debug logging via
sudo python debug-helper.py --mm debug
Then I have captured the syslog via
tail -n0 -f /var/log/syslog > /tmp/syslog
While capturing, I have first clicked "Enable Mobile Broadband" in the Network Manager menu, near the bottom. After some seconds I got an OSD pop-up that I am registered for GSN or so. Now I clicked on "T-Mobile (Telekom) Default" in the "Mobile Broadband" section. The indicator applet icon of the Network Manager started spinning, telling that it is searched for a network. After some time it stopped spinning without connection established. After that, modem-manager is still active in the syslog. I waited some minutes before stopping to capture.
Here is the missing info:
