I could not preview, view, or move a certain message that I had sent yesterday. I restarted Kmail. All messages were listed. None were accessible. After I restarted Akonadi, all the messages were accessible except the one that had not been accessible before. The message is a short text message with a small PNG file attached. The GUI does show a paper clip for the message. I get this message at the bottom of the GUI: "Unable to fetch item from backend (collection 5) : Unable to retrieve item from resource : NO payload size mismatch". Kmail appears to be receiving new messages normally and displaying them normally. Reproducible: Always Steps to Reproduce: 1. Bring up Kmail. 2. Try to preview, view, or move the single message in my sent-mail folder. 3. An error message appears at the bottom of the window, and the message does not appear or is not moved. Actual Results: See "Details". Expected Results: It should have displayed a preview of the message, let me view it in a separate window, and let me move it to another folder.
After a few minutes, Kmail has ceased to access all messages. It also appears to be storing unlimited duplicates of new messages.
However, the little popup windows that show Name, Date, etc., are working normally, even for the message that I originally could not access.
One more detail: I am running XFCE 4, not KDE.
One more detail, but an important one: one of my application programs had inadvertently filled up /home. This would accoutn for all the erratic behavior of Kmail.
Thank you for reporting this bug in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version? If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you!
I doubt that I can reproduce this old bug. I have not used Kmail for years. I may as well mark this bug RESOLVED.
