--- Comment #125 from Allan Sandfeld <k...@carewolf.com> --- Btw. I believe the underlying cause is the same that causes emails you are currently reading to be marked unread again while you are reading it. A sync is often started in parallel with other actions, so for instance you click on a folder it starts syncing, and you are reading an email and it is marked read. You mark it read, but the sync then marks it unread (race condition). The same can happen when moving emails, it might be moved, only to be recreated by the parallel sync, and then moved again, causing two exact copies to exist in the target folder. The transactional atomicy of Akonadi is somewhat questionable with several jobs that consists of multiple database transactions, or is combined with syncing remote servers. I tried looking at the move job, but it is pretty messy. -- You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.
