Hmm. I think this was "silently" addressed in git MM_06 (so in the 0.6 release)... Would you be able to try the package from Quantal (12.10) development release, it should be installable easily and is downloadable from https://launchpad.net/ubuntu/quantal/+source/modemmanager. Look under "binary packages" for your architecture for the 'modemmanager' package (don't need -dbg), and click the first (most recent) version number on the resulting "Publishing history" page.
