Add VBO support to mass update user terms

I tried using VBO, but this does not seem to work.
I get the select blank boxes for the terms, (no term labels, just the correct number of boxes), and no option for update apart of "Modify profile fields" that actually messes up the other fields but does not add any user term.
Is something missing in Views integration?

I also tried User Import, but it totally ignores user terms.

Thanks for help
