Created attachment 627458 [details] Patch fixing the problem. rhts-mk-generate-specfile considers package names appearing in Provides, Requires and RhtsRequires testinfo fields as invalid, if they start with a digit. Then it silently skips including them into the relevant fields in the resulting specfile, leaving a comment instead.
Thanks for the patch, Nikolai. This could be released as a client-only hotfix.
Fixed in rhts-devel-4.52-3.
