Version: 2.1.1 (using KDE 4.6.4) OS: Linux When i "update [a] folder" (maildir), which can contain thousands of emails, hundreds of emails are suddenly marked as unread. Always the same emails. Then marking the mails as read, they remain in a "read" state until the next time i restart kmail and perform the above-mentioned steps. Reproducible: Always Steps to Reproduce: right-click on a folder and click on "Update Folder" Actual Results: Some emails, always the same, are marked as unread. Expected Results: Read mails keep the "read" status. Receiving a new mail and clicking on the folder it got moved to for the first time after kmail starts yields the exact same results.
Same issue here. Found out that removing the .folder_name.index file solves the issue
sorry, wrong bug :-( ignore the post
I can confirm this with kmail2, KDE 4.7 (openSUSE RPMs)
Possible dupe of 276856. Bug 278737 sounds similar too.
This should be fixed with IIRC KDE 4.7.2+, but definitely with KDE 4.8.0. Please reopen if you still see it.
