[Debian-med-packaging] Bug#937698: Help needed for issue in test suite for Python3 (Was: Bug#937698: python-dendropy: Python2 removal in sid/bullseye)

Hi,

I have prepared a fix for this package in Git[1].  Unfortunately I'm
stumbling upon a test suite error which was discussed with upstream
previously.  It happens only for Python3 and was ignored before but
this strategy seems to be inappropriate now after droping Python2.
You can simply reproduce the issue even in the unpackaged source:

$ python3 setup.py test
-setup.py: DendroPy version 4.4.0
-setup.py: using setuptools ('/usr/lib/python3/dist-packages/setuptools/__init__.py')
-setup.py: searching for packages
-setup.py: packages identified:
           - dendropy                
           - dendropy.legacy         
           - dendropy.utility        
           - dendropy.mathlib        
           - dendropy.dataio         
           - dendropy.interop        
           - dendropy.datamodel      
           - dendropy.model          
           - dendropy.calculate      
           - dendropy.simulate       
           - dendropy.utility.libexec
-setup.py: scripts identified:
           - applications/sumtrees/sumtrees.py  
           - applications/sumlabels/sumlabels.py
-setup.py: setuptools command extensions are available

Any hint would be welcome.

Kind regards
