The incorrect calling to zenity via /etc/gdm3/config_error_dialog.patch which should use the --no-markup option for cases when the error messages contain <.

[Hongyi Zhao]

The Ubuntu-specific patch to gdm that ends up calling [zenity --warning](https://git.launchpad.net/ubuntu/+source/gdm3/tree/debian/patches/ubuntu/config_error_dialog.patch), has the following problem:

The patch is probably trying to set the text to something that contains < which means the following text will be considered pango markup. It most likely is not pango markup though. So it need to use --no-markup when calling zenity to avoid the text being considered invalid markup.

Thanks for your report! It's a duplicate of bug #1887252, so I have marked it as such.

But with that said, it would be great if you could read the discussion at the other bug, and let me know if you think that my alternative idea would help.

Thank you for letting me know your alternative nice solution. But
there are so many HTML Character Entities [1-2]. How does your method
deal with all these possible situations?
