To reproduce :
- Compare folders
- Open one difference
- Make a change
- Try to close tab
Whatever you do after, you cannot close tab anymore (traceback appears). If I save the file *before* closing the tab, it works. It seems related to the save dialog.

For those interested in 18.04, the file to replace is:

/usr/lib/python3/dist-packages/meld/filediff.py

and you can replace it with the version:

https://gitlab.gnome.org/GNOME/meld/-/blob/3.18.2/meld/filediff.py

Then saving when closing the tab works as expected.
