Whitespace fixes

Each time the terminate code triggers my Konqueror crashes, i'm substituting the terminate for just waiting the thread to finish and we just ignoring it.

The code has a race condition in which wait() returns false, then we switch to the thread and m_autoDelete is still not set and thus noone will delete the thread. I can add a mutex if you guys think this is unacceptable.

When the 
kDebug() << "Name look up for" << hostName << "failed";
if triggers i do not get a crash anymore.
