Subject: bug#7827: Please do not give an error in help when it fails
Date: Wed, 12 Jan 2011 02:40:14 +0100 [thread overview]
Message-ID: <AANLkTikvbWjC_LiRtS8Lwuq1ZnYtymdf7_ZPH_CmWayd@mail.gmail.com> (raw)
I just got this error when clicking the [back] button in help:
Debugger entered--Lisp error: (error "Selecting deleted buffer")
describe-mode(#<killed buffer>)
apply(describe-mode #<killed buffer>)
help-xref-go-back(#<buffer *Help*>)
apply(help-xref-go-back #<buffer *Help*>)
help-do-xref(214 help-xref-go-back (#<buffer *Help*>))
help-button-action(#<marker (moves after insertion) at 1 in *Help*>)
push-button(214)
call-interactively(push-button nil nil)
That is very unpractical since it prevents from going further back in
the help stack. (Currently I am trying to find my test case which was
some help text 611 chars long, but I do not remember what it was.)
Just put the backtrace in the help buffer instead with a short explanation.
