When Kontact is set to "always start" with specific component (Kontact's configuration --> Kontact), choosing "New massages in" from menu of KMail's system tray notifier (icon) opens also this component, not the KMail's folder in which these new messages are (that is: not the mail component of Kontact).

In my case choosing "New massages in" from KMail's system tray notifier menu opens Summary component, but one can easily reproduce that with Calendar or any other Kontact's component (setting it as a "always start with" component). The thing is that no matter what component is the starting component for Kontact (and whether anyone is set as such), KMail's system tray notifier (icon) should always open only it's own component (i.e. the mail one, and showing the right folder according to my choice from the list of folders with new massages).

That's a bug (in KDE 3.5 KMail's notifier was working well in this respect).
