When attempting to launch catfish after fully updating the system to the latest testing repositories, the application does not start, and an error is shown instead. Researching the error shows it's related to the removal of xml.etree.ElementTree.getiterator() from Python 3.9.

Additional info:
* package version(s): 1.4.13-3
* config and/or log files etc.: See below
* link to upstream bug report, if any: The bug has been fixed upstream, in the master branch (see: ). However, no release contains this fix yet. It may be worth to backport it for the time being.

Steps to reproduce:

Try to launch catfish from the command line:

$ catfish
Traceback (most recent call last):
File "/usr/bin/catfish", line 44, in <module>
File "/usr/lib/python3.9/site-packages/catfish/", line 78, in main
window = CatfishWindow.CatfishWindow()
File "/usr/lib/python3.9/site-packages/catfish_lib/", line 171, in __new__
builder = get_builder(__builder__['ui_file'])
File "/usr/lib/python3.9/site-packages/catfish_lib/", line 109, in get_builder
File "/usr/lib/python3.9/site-packages/catfish_lib/", line 87, in add_from_file
ele_widgets = tree.getiterator("object")
AttributeError: 'ElementTree' object has no attribute 'getiterator'
