XEmacs 21.5.25, tramp from XEmacs packages CVS: Start with xemacs -vanilla. In the scratch buffer, evaluate (global-set-key 'f5 #'find-file-other-frame) Open a dired window on a remote system with tramp (it uses the new default method scp). Press 'f5. The error message is (wrong-type-argument characterp nil) Actually, I had problems in producing a backtrace, and I don't know why. When I set debug-on-error to t, sometimes no reaction appears, no backtrace, nothing. Well, after executing a few other commands, I was eventually able to produce a backtrace: Debugger entered--Lisp error: (wrong-type-argument characterp nil) char-equal(nil ?\t) tramp-completion-mode("/[scp/comedy]/home/schrod/trans/") tramp-file-name-handler(abbreviate-file-name "/[scp/comedy]/home/schrod/trans/" t) abbreviate-file-name("/[scp/comedy]/home/schrod/trans/" t) apply(abbreviate-file-name ("/[scp/comedy]/home/schrod/trans/" t)) dired-handler-fn(abbreviate-file-name "/[scp/comedy]/home/schrod/trans/" t) abbreviate-file-name("/[scp/comedy]/home/schrod/trans/" t) read-file-name-2(file-name-history "Find file in other frame: " nil nil nil nil read-file-name-internal) read-file-name-1(file file-name-history "Find file in other frame: " nil nil nil nil read-file-name-internal) read-file-name("Find file in other frame: ") (list (read-file-name "Find file in other frame: ") (and current-prefix-arg (read-coding-system "Coding system: ")) t) call-interactively(find-file-other-frame) With that information, the error is quite clear: #'event-to-character can return nil and that's not cared for in #'tramp-completion-mode.
