Version: (using KDE 4.4.3) OS: Linux Installed from: Archlinux Packages Since my updating from KDE 4.4.2 to KDE 4.4.3 today, kmail throws an error message when I click on an email in an IMAP folder saying: "Error searching folder. Server replyed: Error in IMAP command received by server" (original error message is in german, I translated it for this bug report). The console output is kmail(4313)/kio (KIOJob) KIO::TransferJob::slotData: mimetype() not emitted when sending first data!; job URL = KUrl("imap://xx@xx.xx:143/INBOX.archiv.Registrierungen/;UID=38;SECTION=BODY.PEEK[]") data size = 1753 I get this message exactly once for every email I click on. Reading the email works fine after I confirm the error dialog. Also, I do not get this error when I click on a cached email. KMail does not crash. It seems to handle the error well. But having to confirm one error dialog for every email is very annoying.
Okay I have fixed this bug by importing a kmail configuration from my other machine that never made the update form 4.4.2 to 4.4.3. This seems to work.
