Hi, There is a bug in kdelibs 4.8.1 that make kmail constantly crashing. It's mostly unusable (crash more or less each time a mail is moved or deleted from imap folder for example). The is a patch against kdelibs in the kde bugzilla (see reference) or directly http://bugsfiles.kde.org/attachment.cgi?id=69550 This completely fixes the issue. I think this could be nice to apply it to the tree. Thanks !
