This case was the original culprit:

ModemManager[20633]: <debug> [1377077909.318827]
[mm-at-serial-port.c:408] debug_log(): (ttyUSB0): <-- '<CR><LF>+COPS:
0,0,"1235",2<CR><LF><CR><LF>OK<CR><LF>'
ModemManager[20633]: <debug> [1377077909.321855]
[mm-broadband-modem.c:3406] modem_3gpp_load_operator_name_finish():
loaded Operator Name: ስ


"1235" was indeed a test operator name; which unluckily triggered the
issue because it is a valid UCS2 encoded string.
