Version: (using KDE 4.3.4) Installed from: Ubuntu Packages I want to auo-hide the RSS newsreader icon in the system tray but KMail should always be visible. This doesn't work because there are TWO Kontact icons in the auto-hide configuration dialog. I don't know which one is RSS and wich one is Kmail. When I disable one of the both are hidden. The tray should display the Kontact components separately. Thanks for fixing.
This bug is still present in KDE 4.4.2. Put both (akregator and kmail) to the system try by setting this in their sepcific preferences dialogs. Now go to the system tray settings and try to hide one of them. You don't know which one is which because both are named "kontact".
This is more a kontact/kmail/akregator bug than a systray bug
