KMaiL: Can't setup D-Bus service. Probably already running.

[Jarosław Staniek]

Hello
I am getting

<unknown program name>(3852)/: KUniqueApplication: Can't setup D-Bus service. 
Probably already running.

in KUniqueApplication::start() when starting KMail on Windows another time.

QDBusConnectionInterface::registerService("org.kde.kmail") returns 
DBUS_REQUEST_NAME_REPLY_EXISTS.

I have no other kmail process started so I am wondering how to avoid such 
cases in general for KUniqueApps.
