Since the latest Kali release (2025.01-04, and all rolling updates since), the new apt install of TheHarvester.py (with apt installed "emailharvester" wrapper script (/usr/bin/emailharvester), the running of the program, even with just a "-h" invocation, throws python syntax errors:

    A tool to retrieve Domain email addresses from Search Engines | @maldevel
                                Version: 1.3.2

options:
  -h, --help            show this help message and exit
  -d, --domain DOMAIN   Domain to search.
  -s, --save FILE       Save the results into a TXT and XML file (both).
  -e, --engine ENGINE   Select search engine plugin(eg. '-e google').
  -l, --limit LIMIT     Limit the number of results.
  -u, --user-agent USER-AGENT
                        Set the User-Agent request header.
  -x, --proxy PROXY     Setup proxy server (eg. '-x http://127.0.0.1:8080')
  --noprint             EmailHarvester will print discovered emails to terminal. It is possible to tell EmailHarvester not to print results to terminal with this option.
  -r, --exclude EXCLUDED_PLUGINS
                        Plugins to exclude when you choose 'all' for search engine (eg. '-r google,twitter')
  -p, --list-plugins    List all available plugins.

Executing an example domain email search (that used to work) also now throws errors, and does not harvest anything (using public/non-key sources).

Is someone looking at fixing this?
