$ rpm -qlp http://fedoraproject.org/extras/development/i386/debug/ytalk-debuginfo-3.3.0-3.fc5.i386.rpm (contains no files) That's a useless debuginfo package, caused by explicit stripping of binaries. Fix: let rpmbuild do the stripping, use %makeinstall instead of %makeinstall-strip (or even better, 'make install DESTDIR=$RPM_BUILD_ROOT' if it works).
I've made the change and it is currently in the build queue.
Judging from the commit messages, you seem to have forgotten that macros are expanded in %changelog too. They sometimes break packages when not escaped (by doubling the '%' in them), and at least produce silly changelog entries for example in rpm -q --changelog.
I know better than that, It's fixed now.
