ModemManager crash with more than one call with Huawei E3131 Modem

[Enrico Mioso]

Hello!!

I am experiencing a crash in Modemmanager, triggered by the following scenario:
1 - Start a voice call from mmcli to my mobile phone.
2 - Answer the call there.
3 - From the mobile phone, call back my Huawei E3131 device.

This results in the following crash: let me know if I can help out more.
