pytest (and DisplayCal itself) segfaults with python-3.12 on wxPython-4.2.1 import and exiting the application #341

If pytest is called with python-3.12 and wxPython is imported like import wx a segmentation fault is raised after the test.

Message that might also be relevant:

<frozen importlib._bootstrap>:488
  <frozen importlib._bootstrap>:488: DeprecationWarning: Type google._upb._message.MessageMapContainer uses PyType_Spec with a metaclass that has custom tp_new. This is deprecated and will no longer be allowed in Python 3.14.

Edit: It does not segfault on the import but after the test has run. Also DisplayCal itself closes with a segfault: Process finished with exit code 139 (interrupted by signal 11:SIGSEGV)

Indeed there is a problem with wxPython-4.2.1 not properly supporting python 3.12 which leads to the application segfaulting after closing. Should be fixed in next release as it is already fixed in the snapshot wxPython-4.2.2a1.dev5626.
