To follow up to my last comment, about not knowing why the Section field was empty, it appears that I was confused about the earlier report. I had gotten the impression that the Section field wasn't empty in the package list file, but that's not true: /var/lib/apt/lists/local/_var_local_mirror_..._Packages contains this stanza:
Package: gsfonts-other Section: Installed-Size: 1728 (...) This seems to be from deb file:/var/local/mirror/debian/ unknown main contrib non-free in sources-local.list. So in fact apt is not buggy in this case; the Packages file is just unusual and hitting a bad corner case of aptitude's grouping code. (in case you're curious, it looks like the ldso stanza also has an empty Section) This should work in the next upload of aptitude. Thanks for the report.
