Bug ID: 388151 Summary: Moving messages to other folder corrupts threading Product: kmail2 Version: 5.6.0 Platform: Debian unstable OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: commands and actions Assignee: kdepim-b...@kde.org Reporter: g...@gmx.net Target Milestone: --- When using threading strategy "Perfect and by references", moved messages are threaded randomly in the tree under the thread starter. In the same folder, the direct parent (from In-Reply-To) is also present, but the message not threaded under it. The resulting folder structure is a complete mess. Restarting kmail and/or akonadi doesn't help. Changing to threading startegy "Perfect only" shows the correct tree, but obviously creates separate trees when a message is missing. Switching back to "Perfect and by references" seems to fix the threading. I have not noticed any problems with threading of new incoming emails, only when moving messages between folders. The messages are moved within the same account, which uses online imap as its backend. The message list aggregation is set to "Threaded" with the following config: Grouping: none Group expand policy: - Threading: perfect and by references Thread leader: Topmost message Thread expand policy: Expand threads with unread or important messages Fill view strategy: Favor interactivity -- You are receiving this mail because: You are watching all bug changes.
