cvs-edit-done calls (ring-insert nil ...)

Using the recently release pcl-cvs 1.46 CVS frontend. I get this *Backtrace* when I try to commit a file: Signaling: (wrong-type-argument number-char-or-marker-p nil) ring-insert(nil "make expiration year 4 digits.\n") #<compiled-function nil "...(120)" [1 ?\n cvs-edit-require-final-newline t y-or-n-p format "Buffer %s does not end in newline.
