The text displayed in the mouse over when hovering over an entry in the message list has nothing to do with the mail corresponding to the entry. In fact, it appears to be text from a completely random e-mail. Reproducible: Always
? Need more infos
I currently have two Akonadi resources, one online IMAP account and one local mail storage (maildir). The effect happens on all mails for which a preview is displayed (interestingly some mails have no preview text in the mouse over). The preview text is completely mixed between those two accounts. I have recently deleted the Akonadi cache from .local/share/akonadi and re-added the local mails directory to clean up the database because my initial mail import was rather old and I wanted to have a fresh start. Please tell me which information would be interesting for you.
Ok, apparently this is not a problem of KMail. It simply shows the RDF property nmo#plainTextMessageContent which already contains the wrong value. So I guess this needs to be reassigned to nepomuk ... or akonadi?
Don't know how did you delete akonadi resource, but you did it and keep nepomuk data, so now it's incoherent. for me it's not a problem with kmail/akonadi/nepomuk it's a specific case unsupported. Regards
Ok, I still don't think that this behaviour is correct, but it's definitely not a problem of KMail, so I'm closing this. I resolved the problem by deleting the Nepomuk database as well.
