symbol's value ...is void: cooding-system-for-write

Hello, I don't know if it is the suitable list to post this question, if not I am sorry. I use xemacs21.4.8-2 (package Debian (testing)) and it runs fine except when I want to print a file: "File->Print doesn't work. I get this message: "symbole's value as variable is void: cooding-system-for-write" However if I do "Option->Advanced->Emacs", after that, "File->Print" works Can someone explained me how can I solved this little problem ? tia for your help. -- Gerard PS In the group Lpr, Command is set to lpr (STATE is don't show as Lisp expression)
