Dear all, reflecting upon Allen's question and Kaushal's answer, I would like to suggest this rule on how to submit bug reports:
Use M-x org-submit-bug-report RET if you installed Org yourself, use M-x report-emacs-bug RET otherwise. This way, Org maintainers who check Emacs bugs are likely to quickly spot if the bug from an old Org version has been fixed already, and users are less likely to share already-fixed bugs on emacs-orgmode. WDYT? -- Bastien
