Description of problem:
gnome-abrt suddenly tries to install files into both %{python_sitearch} and %{python_sitelib} ending with the following error on 64bit architectures:


error: Installed (but unpackaged) file(s) found:
   /usr/lib/python3.9/site-packages/gnome_abrt/__init__.py
   /usr/lib/python3.9/site-packages/gnome_abrt/__pycache__/__init__.cpython-39.opt-1.pyc

   /usr/lib/python3.9/site-packages/gnome_abrt/wrappers/__pycache__/__init__.cpython-39.pyc

While the compiled files is installed into:

  /usr/lib64/python3.9/site-packages/gnome_abrt/wrappers/_wrappers.cpython-39-x86_64-linux-gnu.so


From Python perspective, this doesn't work.



Version-Release number of selected component: gnome-abrt-1.3.5-2.fc33


How reproducible: fedpkg mockbuild




The spec file of gnome-abrt hasn't changed since the successful build on 2020-06-03. Something in the buildroot has changed.

Unfortunately, Koschei doesn't schedule builds, so I can only tell that the following is new since:

I've already tried to downgrade Python to 3.9.0b1, it didn't fix the problem.
I've already tried to downgrade setuptools to 46.4.0, it didn't fix the problem.
I'Ve tired both of the above together, it didn't fix the problem.


Since the next "obvious" candidate is meson, but it is not reported as updated by koschei, I've checked and we have meson-0.55.0~rc2-1.fc33 in rawhide. I've hence tried downgrading meson to 0.54.3, and it fixes the problem.
