Attempted to rebuild for matio, but there's a gobject-introspection error. 8.10.1 has the same behaviour.

Hello,

This is the first reminder (step 3 from https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs).

If you know about this problem and are planning on fixing it, please acknowledge so by setting the bug status to ASSIGNED. If you don't have time to maintain this package, consider orphaning it, so maintainers of dependent packages realize the problem.

The gobject-introspection error is https://github.com/libvips/libvips/issues/1836.

Fixed in 8.10.1-1.
