PyOtherSide fails to build with Python 3.9

[M4rtinK]

So Fedora is yet again getting ready to include the latest Python version, which yet again managed to break the PyOtherSide package build. ;-)

This time it looks like the build was successful, but one of the tests fails:

Executing(%check): /bin/sh -e /var/tmp/rpm-tmp.A3Csrv
+ umask 022
+ cd /builddir/build/BUILD
+ cd pyotherside-1.5.8
+ xvfb-run ./tests/tests

I guess this is the test that fails:

pyotherside/tests/tests.cpp

Line 253 in c67604b

TestPyOtherSide::testPyObjectConverter()

Maybe some C level Python API changes in 3.9 ?

More data & detailed logs from the build failure can be seen in the Fedora bug:

Thanks in advance & let me know if there is something I can do further help you track this down. :)

Also tagged version 1.5.9 with the fix for your convenience. Thanks for the bug report!

Wow, that was fast! :) I've built 1.5.9 for Fedora, so it should be ready for when Fedora switches to Python 3.9. :)
