Comment 6 for bug 1430700

Confirmed on krillin, devel-proposed #141.

I reproduced using the scripts.

The set-3g-slot command finishes, but leaves the modem in a bad state:

root@ubuntu-phablet:/usr/share/ofono/scripts# ./list-modems
[ /ril_1 ]
    Interfaces = org.ofono.MtkSettings
    Lockdown = 0
    Emergency = 0
    Powered = 0
    Type = hardware
    Online = 0
    Features =
    [ org.ofono.MtkSettings ]
        Has3G = 1

[ /ril_0 ]
    Interfaces =
    Lockdown = 0
    Emergency = 0
    Powered = 0
    Type = hardware
    Online = 0
    Features =

The reboot fixes this, and then when I try to offline /ril_0, the script throws an exception when the DBus reply timeout expires.
