python3-apport will crash if current directory has been unlinked

Description: Ubuntu 18.04.5 LTS
Release: 18.04

I have also checked the code for Ubuntu 20 and the specific code looks identical to me.

From package:python3-apport
file: /usr/lib/python3/dist-packages/apport_python_hook.py

The follwing code will crash if current directory has been removed, os.getcwd() does not like that directory is gone:
        # apport will look up the package from the executable path.
        try:
            binary = os.path.realpath(os.path.join(os.getcwd(), sys.argv[0]))
        except (TypeError, AttributeError, IndexError):
            # the module has mutated sys.argv, plan B
            try:
                binary = os.readlink('/proc/%i/exe' % os.getpid())
            except OSError:
                return

FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp_6ehbyrh'
Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 76, in apport_excepthook
    binary = os.path.realpath(os.path.join(os.getcwd(), sys.argv[0]))
FileNotFoundError: [Errno 2] No such file or directory

The try-except condition above maybe should also contain FileNotFoundError to handle this error.
