Since xpra has the following line in its spec file:

    Requires:    python3-Pillow

it was broken by the recent change in Factory:

- add sle15_python_module_pythons (jsc#PED-68)

Because that effectively stops it from building python3-Pillow in Leap 15.6 and
SLE-15-SP6 Package Hub. This is because Leap 15.6 and SLE-15-SP6 provide both a
default Python 3.6 and an optional Python 3.11.

This makes it impossible to install xpra, even though xpra is part of the
distro.
