typecatcher crashes on launch

Bug Description

I recently upgraded to hirsute 21.04 and just discovered typecatcher doesn't launch. A couple of web searches implies some deprecated python issues; I don't know what version python I was running in Ubuntu 20.10.

This is what I see when trying to launch it from a terminal:

~$ typecatcher
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/typecatcher_lib/Application.py", line 30, in on_activate
    self.window = TypeCatcherWindow.TypeCatcherWindow()
  File "/usr/lib/python3/dist-packages/typecatcher_lib/Window.py", line 47, in __new__
    builder = get_builder('TypeCatcherWindow')
  File "/usr/lib/python3/dist-packages/typecatcher_lib/helpers.py", line 44, in get_builder

    ele_widgets = tree.getiterator("object")
AttributeError: 'ElementTree' object has no attribute 'getiterator'
~$ python --version
Python 2.7.18

I read that font-manager had the feature I needed at the moment so I used the Software Center to install it. For some reason the flatpak version it chose worked at first then crashed. So I uninstalled the flatpak and used apt to install the version in hirsute, which has worked just fine.

I think it's possible I have some weird cruft in my local font caches or somewhere leftover from the upgrade from groovy 20.10.

I successfully used font-manager to install a font in local storage (and font-manager seeing the two Google fonts typecatcher had installed several months ago)

HOWEVER even after a couple of reboots, typecatcher is still crashing on launch.

Working on the local cache theory I tried running typecatcher in another user account on this system but which did NOT have any user account installed fonts. It crashes in the same way as shown at top; font-manager runs fine, and confirms no locally-installed fonts in the other user's account.

I just fired up a VM of 21.04 Hirsute and typecatcher crashes with the same error on a new VM

Thanks for reporting.

I can confirm that typecatcher 0.3-1.2 crashes when I attempt to run it on Ubuntu 21.04. I found a similar bug report in Debian which lists the same stack trace so I have attached a bug watch.
