Still no luck. I restored the machine to a previously working state, and
then upgraded both procps and *selinux*. Immediately after the upgrade ps
stopped showing contexts again.

When I get some time I'll start with a fresh F-7 install and then upgrade
to rawhide. Maybe some intermediate update broke things beyond repair.
I think I found the problem.
'ps' tries to find and open 'libselinux.so'. At some point this library was
moved from libselinux to libselinux-devel. Since I didn't have
libselinux-devel installed, ps failed to load the library and find the selinux
context information.
Installing libselinux-devel fixes the problem.
I see three possible ways to fix this:
1) Move libselinux.so back to libselinux
2) Add 'Requires: libselinux-devel' to procps
3) Fix ps to load libselinux.so.1 instead of the unversioned .so file.
