QTimer::singleShot(0, this, SLOT(slotFinished() )) doesn't work either,
because then slotFinished() tries to remove a job that hasn't been
scheduled yet. 

the output is 

QObject::disconnect: Unexpected null parameter

Program received signal SIGSEGV, Segmentation fault.
KIO::Slave::isAlive (this=0x0) at ../kio/slave.h:60
60              bool isAlive() { return !dead; }

backtrace: 

#0  KIO::Slave::isAlive (this=0x0) at ../kio/slave.h:60

with other words m_slave isn't set correctly at that point, so it segfaults. 

I'm afraid it isn't that easy ;-)
