Version: (using Devel) OS: Linux Installed from: Compiled sources KDE 4.3.80 I do not remember this in 4.3; in 4.4 it happened several times. I do not know how reliably reproduce it, but as far as I can reconstruct what was happening: - I had kmail with all messages read - logout from KDE without closing KMail - start KDE again - KMail is started automatically as part of saved session. On startup it displayed one "new" message in last folder I was viewing before logout. There was exactly one new message before logout that I viewed and deleted - entering this folder cleared "new messages" on folder (bold font) but left 1 unread message in tray icon - now this tray icon is "stuck" - I have no way to remove new message indication from it.
You reported against a pre-version of KDE 4.4. Has this improved since then?
I still see it sometimes after a crash. It is just that now my system crashes less often :)
I'm seeing this too after closing the session without closing kmail first. You can get rid of the icon by clicking it twice (to minimize kmail to tray and restore it)
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.
