[Bug 2051512] Re: apport ftbfs with Python 3.12 as the default

[Simon Chopin]

** Also affects: python3.12 (Ubuntu)
   Importance: Undecided
       Status: New

** Description changed:

-    debian/rules override_dh_auto_test
+ [Description]
+ 
+ Python 3.12 gzip.GZipFile.write() outputs truncated data in some cases
+ (maybe all?)
+ 
+ [Test Plan]
+ 
+ Run the following script:
+ 
+ import gzip
+ import io
+ out = io.BytesIO()
+ gzip.GzipFile("foo", mode="wb", fileobj=out, mtime=0).write(b"FooFoo")
+ # print(out.getvalue())
+ print(gzip.decompress(out.getvalue()))
+ 
+ Expected output (as on Python 3.11):
+ FooFoo
+ 
+ Buggy output (tail end of the stack trace):
+ EOFError: Compressed file ended before the end-of-stream marker was reached

  Python 3.12 gzip.GZipFile.write() outputs truncated data in some cases
  (maybe all?)

  [Test Plan]

  Run the following script:

  import gzip
  import io
  out = io.BytesIO()
  gzip.GzipFile("foo", mode="wb", fileobj=out, mtime=0).write(b"FooFoo")
  # print(out.getvalue())
  print(gzip.decompress(out.getvalue()))

  Expected output (as on Python 3.11):
  FooFoo

  Buggy output (tail end of the stack trace):
  EOFError: Compressed file ended before the end-of-stream marker was reached
