diff-mode

Using PCL-CVS and pressing `=' on a file brings out this message: (1) (error/warning) Error in process sentinel: (wrong-type-argument stringp nil) with "Parsing differences..." in the modeline. Seem to be `diff-mode' that's having problems. This is with "xemacs -no-init-file". I would check if my XEmacs packages are up to date, but I get the following error when I select "Update package index" from the Options menu. (1) (error/warning) Error in process filter: (ftp-error FTP Error: CWD 550 /pub/gnu/xemacs/packages/package-index.LATEST.pgp/: Not a directory. failed: )
