Comment # 1 on bug 1110984 from Manfred Hollstein

Hmm, installing the following packages solves the traceback and allows to send
a fax again, so I'm going to close this ticket:

  python3-Pillow python3-olefile python3-reportlab

FWIW, this was a copy of the named 42.3 system, and I have solver.onlyRequires
set to true.
