I made some backtraces of the (as far as I see it) processes that are running 
when the deadlock appears: Ksplash, dcopserver and the two KLauncher 
processes.

I also assume that the second DCOPClient::attachInternal() call is from 
ksplash.

Here are the backtraces:
(Are there better ways to include long logs like this?)
