Thank you for the report. The issue is indeed present in 1.2.1. It is
due to a conflict in short option letters. I just committed a fix for
this, but don't intend to roll a new release just for this single fix in
an obscure option to an experimental binary. 1.2.2 will see this fixed
but may take some time, e.g. until another translation comes in.

I would advise Debian to not include the --enable-experimental option in
the configure call for this package. The code for those parts receives
too little attention to be let loose on the masses, imho. That is the
reason why I don't enable building those parts by default.
