ModemManager 1.10.2 crashes
I just built latest ModemManager-1.10.2 together with libmbim-1.18.2 and libqmi-1.22.4 since my distro (LMDE3, which is based on debian9) ships with old versions of the three and I want to try a recent ModemManager because the shipped one segfaults when talking to my broadband modem Alcatel, but this is another story. After booting my system, I ran 'ps -A' and I saw no tasks called ModemManager. Launched ModemManager on the command line:
$ sudo ModemManager
ModemManager[2150]: <info> ModemManager (version 1.10.2) starting in system bus...

ModemManager: symbol lookup error: ModemManager: undefined symbol: mm_kernel_event_properties_get_type
which sound a bit weird, since the build was successful (I also ran the 'make check' before installing). What am I missing? Do I need to update some further libraries?
