I am trying to build a SRPM using COPR for a Python package, and rpkg creates what I think is an incorrectly created tarball for inclusion into the SRPM.

The package in COPR is here: https://copr.fedorainfracloud.org/coprs/andymaier/python-nocaselist/package/python-nocaselist/

The COPR package is set up to use rpkg for building, i.e. with these settings in COPR:

Source Type: Build from an SCM repository
SCM type: git
Clone URL: https://github.com/pywbem/nocaselist
Committish: andy/fedora-packaging
Subdirectory: .
Path to .spec file: packaging/fedora/python-nocaselist.spec
Build SRPM with: rpkg

When COPR invokes rpmbuild, it fails when unpacking the nocaselist-1.0.2.tar.gz file and trying to cd into its nocaselist-1.0.2 directory, because that tarball has been created to contain its content below a python-nocaselist-1.0.2 directory, and not the expected nocaselist-1.0.2 directory. The error is shown at the end of this log file: https://download.copr.fedorainfracloud.org/results/andymaier/python-nocaselist/fedora-rawhide-x86_64/01673307-python-nocaselist/builder-live.log.gz

I must admit that I don't fully understand how the tools invoke each other, but later COPR runs from the copr-cli command using a locally built tarball succeed, and only when I use the build with rpkg described above, it fails.
