Bug ID: 453383 Summary: Reply mails are shown in wrong thread after being moved to a different folder (in Kontact) Product: kmail2 Version: 5.20.0 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: folders Assignee: kdepim-bugs@kde.org Reporter: dev-...@felsenfleischer.de Target Milestone: --- Created attachment 148558 --> https://bugs.kde.org/attachment.cgi?id=148558&action=edit Comparison of inbox view between Kontact and Kmail I’ve been observing this issue now for a very long time now. I thought something this obvious must be noticed easily. But it seems I hit a niche and it just happened again, so I finally decided to report it. STEPS TO REPRODUCE I just sent replies to two different mail threads in an IMAP account. KMail stored the replies in the Sent folder, as usual. I went to the folder, selected both mails and moved them to the Inbox folder, so they may be shown within their respective threads. OBSERVED RESULT The mails were shown in the wrong thread: replay to thread A is shown in thread B and vice versa. EXPECTED RESULT The mails should appear as reply to the correct mail. Operating System: Arch Linux KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 Kernel Version: 5.17.5-arch1-1 (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-5200U CPU @ 2.20GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 5500 ADDITIONAL INFORMATION One very interesting bit of info that I found out just now: the issue only appears in Kontakt. I closed Kontact and opened KMail as standalone application, and in there the threads were correct. Then I closed KMail and reopened Kontact, and the mails were mixed up again. I did this twice, both times with the same result. So perhaps this is a Kontact thing, or an Akonadi bug? I haven’t tested yet what happens if I move mail in standalone-KMail, so whether the (akonadi?) data is garbled during the move or during display. I also looked at the mail source to make sure the In-Reply-To header was correct. But I already knew it was so, because when I sync the account with offlineimap and view it in mutt, the thread is also correct. I have akonadiconsole installed, so I am happy to provide deeper info if required. While preparing the screenshots, I also noticed that the structure of the lower thread is different between the two programs (see circles in the image). Apparently there has been a similar hickup in the thread before. -- You are receiving this mail because: You are the assignee for the bug.
