I have just encounted this error and was fairly puzzled until I
investigated further. A simple google search for the error message shows
quite a lot of people having the same issue and a few upstream bug
reports which simply get closed as "Debian's problem". If I understand
the packaging correctly, simply rebuilding this package should update
the various wheels automatically and fix this? Please can this happen.

Thanks,
James
