"emacs -Q" in a VC directory, preferably one in which updates take more than a few seconds (large tree, distant/slow server, or both). 2. "C-x v d" to get into the *vc-dir* buffer, and *immediately* type "n" (vc-dir-next-line) before the buffer has any file lines. This gives me a "wrong type argument" error (backtrace below) when ewoc-goto-node tries to treat "nil" as a node. The tweak to ewoc-goto-next (below the backtrace) produces a better error message, but is still too generic. -- Bob Rogers http://www.rgrjr.com/ ======================================================================== Backtrace: Debugger entered--Lisp error: (wrong-type-argument arrayp nil) ewoc-goto-node([cl-struct-ewoc # (lambda (&rest --cl-rest--) (apply #[...
