Does a report exist for this bug with the project's home (upstream) and/or another distro?

This appears to be the same issue as Ubuntu bug #2152641:
https://www.mail-archive.com/ubuntu-bugs%40lists.ubuntu.com/msg6276796.html

The Ubuntu bug references an upstream Cinnamon fix:
https://github.com/linuxmint/cinnamon/commit/02977f15dbb0ffc55ae28b3f52d955cd7c63a84e

Expected behaviour

Opening Cinnamon Settings -> Applets, Desklets, Extensions, or Themes and selecting the Download tab should display the list of available items from the Cinnamon Spices repository.

The download page should populate normally and allow browsing and installation of applets, desklets, extensions, and themes without errors.

Actual behaviour

The Download tab in Cinnamon Settings does not display any available Applets, Desklets, Extensions, or Themes.

When opening the Applets/Desklets/Themes download section, the list remains empty. Running cinnamon-settings from a terminal shows an exception:

Loading Applets module
Traceback (most recent call last):
  File "/usr/share/cinnamon/cinnamon-settings/bin/ExtensionCore.py", line 1060, in on_page_shown
    self.build_list()
    ~~~~~~~~~~~~~~~^^
  File "/usr/share/cinnamon/cinnamon-settings/bin/ExtensionCore.py", line 1034, in build_list
    row = DownloadSpicesRow(uuid, data, self.spices, size_groups)
  File "/usr/share/cinnamon/cinnamon-settings/bin/ExtensionCore.py", line 770, in __init__
    score_label = Gtk.Label(self.score)
  File "/usr/lib/python3.14/site-packages/gi/overrides/__init__.py", line 357, in new_init
    return super_init_func(self, **new_kwargs)
TypeError: Must be string, not int

The issue appears to be caused by the Spice metadata "score" value being returned as an integer while cinnamon-settings expects a string.

Steps to reproduce

1. Install Cinnamon 6.4.13.
2. Open Cinnamon Settings from the terminal: cinnamon-settings applets
3. Select the "Download" tab.
4. Wait for the list of available items from Cinnamon Spices to load.

The Download tab fails to populate and an exception is raised:
TypeError: Must be string, not int

The same issue also occurs with Desklets, Extensions, and Themes.

Start with the ExtensionCore.py traceback, especially DownloadSpicesRow and the Gtk.Label call, then compare the referenced upstream Cinnamon commit 02977f15dbb0ffc55ae28b3f52d955cd7c63a84e. Reproduce with cinnamon-settings applets and verify that the Download tabs for applets, desklets, extensions, and themes populate without the TypeError.
