Subject: bug#17210: 24.3.50; help mode [back] link to a C-h b keybind listing fails with message "Current buffer is not in Help mode"
Date: Sun, 06 Apr 2014 16:47:36 -0700 [thread overview]
Message-ID: <5341E798.4060004@iankelling.org> (raw)
Repro steps:
emacs -Q
C-h b
click function name link
click back
expected:
go back to the C-h b keymap listing
acutal
in echo area: "Current buffer is not in Help mode"
the help buffer does no change.
The problem does not always happen, but it seems consistent on the first try in a
fresh emacs. Toggling debug on error, gives this trace:
Debugger entered--Lisp error: (error "Current buffer is not in Help mode")
signal(error ("Current buffer is not in Help mode"))
error("Current buffer is not in Help mode")
