Comment 32 for bug 1091663

OK, I've tried with both those network-managers, but kept getting that same DBus error.

I had to tweak a few things to build the network-managers:
- added -u--ignore-missing-info to dh_shlibdeps in debian/rules, to avoid missing info for a package (I think it was libmm-glib)
- removed libmm-glib-dev from dependencies, as I couldn't find that package (i.e. deleted the line from debian/controls)
- built with --builder='debuild -b -us -uc' to avoid GPG error

Starting ModemManager --debug manually still gives:
[main.c:114] name_lost_cb(): Could not acquire the 'org.freedesktop.ModemManager1' service name

And in the syslog this happens
...
 ModemManager[945]: <info> Loaded plugin 'Infineon'
...

(the whole syslog is attached).
