Version: 1.11.3 (using KDE 4.2.3) OS: Linux Installed from: Fedora RPMs I'm running a dovecot/IMAP server under CentOS-5.3 on my desktop, reading the mail with KMail on my laptop. I have what seems a venerable and well-documented problem/bug; when I click on "Check Mail" I get an error message "Error while getting folder information" ... Actually, this doesn't appear to have the slightest effect on kmail, which works perfectly if one just presses Continue. But I have worked out that the cause of the problem is that there exists a kind of ghost folder, "uidvalidity", which is listed among the folders on the kmail page but does not in fact seem to exist in my maildir on the server. Deleting the folder under kmail has no permanent effect; it simply re-appears when I re-start kmail. This bug/feature seems to have been present for years, which I suppose is par for KDE. To make it as difficult as possible to diagnose, the error message on the kmail page is incomplete, even when expanded to the whole screen. In particular it does not specify (on the visible part) what folder is causing the problem. Nor is the error listed with other dovecot information in /var/log/messages .
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
