--- Comment #6 from Michael Catanzaro <mcatanzaro at igalia.com> ---
A couple tips that might help:

My recommendation for debugging login screen issues is to set up a VM and SSH into it. If you use GNOME Boxes, run ifconfig in the VM, note the IP address of the Ethernet interface, 'systemctl enable sshd' and 'systemctl start sshd'. Then you can get a real console from the host, and can connect to your greeter with 'gdb -p'. You can also use a spare laptop or something instead of a VM.

It would help to put G_DEBUG=fatal-warnings in your environment, then it will crash on the first occurrence of the error and you can get a real backtrace.

The easiest way would be to remove as much code from your greeter as you possibly can without making the bug go away; then the smallest amount of code that reproduce the issue is a test case we can use to debug this. Ideally it would be possible to reproduce the issue by running a little test program in a normal session that doesn't depend on lightdm.
