| Status | Subtype | Assigned | Task | ||
|---|---|---|---|---|---|
| Resolved | None | T51250 Add an option to make email subjects for new bugs compatible with gmail's threading | |||
| Resolved | Aklapper | T51597 Upgrade Bugzilla to 4.4 |
Wasn't aware that GMail ignores Message-ID, In-Reply-To and References headers so workarounds are needed for just one freemail provider. :-/
This will get fixed by upgrading to Bugzilla 4.4, see https://bugzilla.mozilla.org/show_bug.cgi?id=663747
For the original subject "Install GmailThreading extension", this is a WONTFIX.
https://bugzilla.wikimedia.org/userprefs.cgi?tab=settings now offers "Add 'New:' to subject line of email sent when a new bug is filed" which users can enable for themselves.
