If a dir is written with a trailing slash as a parameter for %allow_python3_import_path or %add_python3_path, it doesn't work completely correctly. Example: http://git.altlinux.org/people/sem/packages/?p=firewalld.git;a=commitdiff;h=2f6a496278d851d906afa30b7d11f41f3da087a0 -- with a slash, the autoprovs are not generated.
