###############################################################################


I have checked the files and found that pdfcrop calls etex, and that reads the file
/usr/share/texlive/texmf-dist/tex/generic/config/language.def
which contains the line

\addlanguage{arabic}{zerohyph.tex}{}{}{}

\addlanguage is defined in file
/usr/share/texlive/texmf-dist/tex/plain/etex/etex.src

The macro crashes when called with empty parameters #4 or #5,
because \chardef= needs a numeric value.


I modified this file to use a default value when parameters #4 or #5 are empty.
I have chosen the value "1" as default value ; I am not sure if this is right.
But pdfcrop works again with this modification.
