By looking closely, somewhere in filter configuration (mime.convs?) is 
messed up.

clause        '-sOutputFile=/dev/fd/3' '/dev/fd/0' 3>&1 1>&2

means:    to read data from stdin and send result to stderr (not stdout, 
weird);
then, redirection says to redirect 3 (stderr) to 1 (stdin, even weird), 
this loops;
and then redirect 1 (stdin) to 2 (stdout), thus input (stdin , 1) is 
empty because
it is redirected to stdout (2) and all input are directly sent to stdout 
(bypass the filter ???).
