KIO::ListJob::entries emits twice for folders with 100+ entries. Why?

Err, KIO doesn't really support threads. You have to run KIO in the main 
thread. Well if you connect the job to slots in another thread and never call 
any KJob API from that thread, I guess it can work out ok, but only then.

SlaveBase is in the kioslave, not in your application. So you need to kill 
kio_file and you need to type "kdeinit4" in a terminal.

Otherwise kio_file gets started via an old kdeinit4 which has the old libkio 
loaded (the one without your debug output).

I recommend kDebug over gdb for this, especially for a method that is called 
500 times.

Well yeah you already posted a test program iirc.
Otherwise here's mine: http://www.davidfaure.fr/2012/kio-listdir.zip
