The python3-pdfminer RPM requires both Python 2 and Python 3.
Except in very special circumstances, there is no need for one package
to drag in both Python stacks. Usually, this is a packaging error: for
example, a stray "/usr/bin/python" shebang in a Python 3 package can
introduce a Python 2 dependency.
Please split your package, or remove the stray dependencies.
There is a section on shebangs in the Python RPM Porting Guide 
which covers this issue.
It's ok to do this in Rawhide only, however, it would be greatly
appreciated if you could push it to Fedora 24 as well.
If anything is unclear, or if you need any kind of assistance, you can
ask on IRC (#fedora-python on Freenode), or reply here. We'll be happy
to help investigating or fixing this issue!
Oops. I thought I'd fixed this a few months ago, but it's probably broken again now that I updated pdfminer yesterday (pdfminer's library files, not just its scripts, all have shebangs on them, sadly). I'll take a look.
Ah. I updated the patch for doing this but at some point apparently commented out the Patch line in the spec file, so it wasn't being applied. Whoops!
Building for rawhide and F24; will push updates.
