Hi, I believe this issue was introduced by this patch:
https://sources.debian.org/patches/libmateweather/1.26.3-3.2/0001_libsoup3.patch/
. However, it was recently fixed by the upstream author, but Debian's patch
hasn't been updated yet. For details, please see:
https://github.com/mate-desktop/libmateweather/pull/133#discussion_r2045046451
I confirmed that manually building the up-to-date upstream pull request and
replacing /usr/lib/x86_64-linux-gnu/libmateweather.so.1.6.9 with the newly
built libmateweather.so.1.6.9 fixes the issue. Thanks.
