Shredder GUI crashes on startup: GLib has no attribute 'option'

[lc31dns]

Hello,

I hit a GUI startup crash with Shredder on Kali.

Environment:

• rmlint-gui 2.10.2
• Python 3.13.12
• GLib 2.88.0
• Kali GNU/Linux 2026.1

The launcher and rmlint --gui were both crashing at startup.

Traceback:
AttributeError: 'gi.repository.GLib' object has no attribute 'option'

After checking the installed code, shredder/cmdline.py still uses:

• GLib.option.OptionParser
• GLib.option.make_option

On my system:

• hasattr(GLib, "option") is False
• hasattr(GLib, "OptionContext") is True

I applied a local patch replacing the argument parsing in parse_arguments() with Python argparse, and after that rmlint --gui started working again.

So this looks like a compatibility issue in Shredder’s GUI argument parsing, not a dock/launcher issue.

If useful, I can provide the local patch I used.

Thanks.

Thanks, this looks related indeed.

On my side, replacing the old GLib.option-based argument parsing in shredder/cmdline.py with argparse made rmlint --gui work again.

So this seems to confirm the crash is caused by the old option parsing API no longer being available.

They suggest to use OptionContext, but they've also removed it !
See https://gitlab.gnome.org/GNOME/pygobject/-/merge_requests/499

Switching to Python stdlib (and that's better IMHO).
