That is a very very very old ModemManager version...

For Ubuntu Trusty, you may want to try with this PPA, which has a much
more recent version:
https://launchpad.net/~aleksander-m/+archive/ubuntu/modemmanager-trusty

If you still get the segfault, please try to gather MM debug logs:
https://www.freedesktop.org/wiki/Software/ModemManager/Debugging/

Or better, install debug symbols and get a proper gdb backtrace.

Also, note there is a ModemManager specific mailing list, here:
https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel

Cheers!
