First, it seems to me that this is a frontend to update-alternatives (could be wrong) and as such I would expect libfm-pref-apps to affect update-alternatives, e.g. adding an option to libfm-pref-apps should add to update-alternatives. It is not the case, however. Similarly, if all the options are the same, changing to a different option, does not change any behavior in update-alternatives.
If I am wrong and libfm-pref-apps acts entirely differently and outside of update-alternatives, I would seek to question its utility. It would appear redundant and problematic, especially considering the user-friendly option (libfm-pref-apps as update-alternatives requires the terminal) doesn't work as expected.
I should also add in 12.04 xxxterm does not install itself as an alternative to x-www-browser, but that's more of a problem with the xxxterm package.
