[Debichem-devel] Bug#1078148: bkchem: Not starting with Python 3.12: No module named 'imp'

[Vincent Meille]

Package: bkchem
Version: 0.14.0~pre4+git20211228-3
Severity: important
Tags: patch

Dear Maintainer,

after showing its logo, this application crashes under the Python 3.12 
environment with this trace:

'''
Traceback (most recent call last):
   File "/usr/share/bkchem/bkchem/bkchem.py", line 185, in <module>
     myapp.initialize()
   File "/usr/share/bkchem/bkchem/main.py", line 116, in initialize
     self.init_modes()
   File "/usr/share/bkchem/bkchem/main.py", line 490, in init_modes
     import imp
ModuleNotFoundError: No module named 'imp'
'''

This is related to the imp module removal in Python 3.12 [1].

I produced the joined patch with the help of the link above.

Regards,
Vincent.
