In the short term, no. In the longer run, though, I'd propose to make debhelper generate files in /usr/lib/mime/packages/ for any packages that install .desktop files in /usr/share/applications/, and then change update-mime to no longer parse the .desktop files itself (unless explicitly told to by a command-line option, perhaps). This may require some adjustments to Debian policy. I haven't researched the development history of update-mime, but the parsing of the .desktop files feels like it was added as an afterthought and doesn't fit in very well; I would either drop it or redesign the whole thing.
