Esteemed maintainers,

This is a follow-up to https://issues.guix.gnu.org/43200 and addresses the second issue mentioned there: breeze icon theme not being found by kdenlive.

Attached are two patches: the first makes the breeze icon theme available to kdenlive during runtime by setting XDG_DATA_DIRS to include the 'share' directory of the breeze package. The second updates kdenlive's source url to follow permanent redirection as reported by `guix lint`.

Thank you.
