Hi, I have a GMail account with Inbox and another folder. I have three related messages, one (#1) in Inbox and two (#2 and #3) in the folder. After selecting the two messages in the folder, I dragged them them into Inbox (move). The three messages were threaded together in Inbox, but somehow #3 was replaced by a duplicate of #2! Now in KMail it looks like I have two identical messages in this thread following #1. This seems to be a local cache bug. The GMail interface shows the original email #3, now in Inbox. Poking around in Akonadi Console (while pretending I know what I'm doing in here) I see Remote ID's differ by 1, and so do Unique ID's. The "later" one, which I guess is #3, seems to have Revision 2, whereas the other (presumably #2) has Revision 1. Not sure what that implies. Let me know if I can provide more info, though at some point I will need to invalidate this local cache to fix the problem. Best, Brendon
Still happens, so updating this bug's meta-data. (I had actually forgotten I'd already reported this, and only realized after going through the process of searching for similar bugs, finding this report, and seeing the original reporter's name was strikingly familiar...)
I have now seen this happen when selecting two unrelated emails at once and moving them into another folder: the pair turns into duplicates of one of the emails. If I clear the Akonadi cache for that folder, when the messages are re-downloaded, they appear correct.
