Got to this error too, but this commit https://github.com/analogue/iotop/commit/f9f3924b9d187cf026785b1533ef66ffc631d029 already fixes the issue. Perhaps installing from source will fix the issue for all of you, most likely distro has outdated package.

Happens for example when supplementary group list for the process is empty, when parsing Groups:\n.
