CVS commit by lunakl: 

Stop previous startup notification for the application immediately if new one is set.
In #99205 the dcopstart-like functionality in kfmclient launches konqueror,
waits for it to register with DCOP and then it uses. And since it's kinda unreliable
when having two kfmclient's started at the same time they may both use
the same konqueror and ignore the second one.
BUG: 99205
