pylint #4591 pylint -- Doesn't purge all files after piuparts Install+Upgrade+Purge test [open]

I have been analyzing packages for the piuparts test, and have observed that pylint fails the piuparts because it doesn't purge some files.

The gzipped log of the piuparts run for pylint is attached. The problem is that the process

Install Stable pylint -> upgrade to sid -> purge

seems to let the following file remain unremoved:
