Description of problem: IIUC, current version of this package has been built with python3.5, but the latest default version in Fedora 26 is python3.6. This is why Frescobaldi, which depends on this package for the PDF rendering, cannot find the popplerqt5 module.

This is embarassing.. I was sure the package was installed on my laptop, but I had installed it only on my desktop computer few days ago. The old versions of previous python versions were compiled from source by me. Sorry for the noise. PS I guess that if I had used python-bugzilla, I'd have been warned that I was about to report a bug of a package not installed? (that's what reportbug in Debian would have done)
No worries. :) Possibly, I've never availed myself of it so I'm not sure.
