Thanks for the bugreport!

Which of the workarounds would you consider best? Could you perhaps 
provide a proposed patch?

And would you maybe be interested in helping maintain this package? That 
would be awesome - and no, you do not need to be a Debian developer to 
help, neither do you need to understand all parts of the packaging 
routines: I am still around and I know the packaging parts pretty well.
