--- Comment #6 from Jonathan Marten <j...@keelhaul.me.uk> --- Created attachment 80486 --> https://bugs.kde.org/attachment.cgi?id=80486&action=edit Zip archive of test messages Test case attached, public messages with no personal information included. These Bugzilla mails are unchanged apart from deleting irrelevant "Received" headers and removing the "New:" prefix from the thread starters so that the subjects are identical. To reproduce: Create a new empty folder in KMail. >From within the zip archive, click on each of the files in turn to open them with KMail View. Do not do this with the 'thread2-1' message for the moment. Context menu - Copy Item To - the new folder The folder should now have five emails in it. With the aggregation options set to "Standard Mailing List", observe that the 3 messages referring to bug#314981 are threaded but the 2 messages referring to bug#279188 are not. Even though the thread starter is not present, they should be grouped by subject. Then copy in the 'thread2-1' message. Observe that the second set of messages become threaded. To confirm, delete one of the thread starter messages and observe that the remaining ones become unthreaded again. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
