* What exactly did you do? - Started Emacs with no configuration (debug-on-error set) - Opened an org-mode file with a text block - Hit C-' - The source code block becomes highlighted, An edit buffer appears; code from the block is inserted into the buffer.
* What did you expect to happen? I expected to be able to edit the source, then insert it into org-mode file with another invocation of C-' * What happened instead? - The buffer appears, but an error is generated. - C-x C-s prompts for a filename to save buffer in instead of inserting it into org file. - C-c ' is undefined, so it will not let me close the edit buffer and go back to the file. *Backtrace* Debugger entered--Lisp error: (wrong-type-argument listp t) delete((org-filtered) t) remove((org-filtered) t) org-move-to-column(0) org-edit-src-code() org-edit-special(nil) funcall-interactively(org-edit-special nil) call-interactively(org-edit-special nil nil) command-execute(org-edit-special) Emacs : GNU Emacs 25.1.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.14.13) of 2016-05-31 Package: Org-mode version 8.2.10 (release_8.2.10 @ $HOME/usr/share/emacs/25.1.50/lisp/org/)
