That's the problem. The m_getJob->suspend() call in FileCopyJob::slotData
is supposed to actually suspend the get job, until the put job got the data.
It has no time to get it, in the current situation:

kwrite: DataProtocol::DataProtocol()
kwrite: kio_data::get(const KURL& url)
kwrite: kio_data::get -> sending outdata

kio (KIOJob): FileCopyJob::slotData
kio (KIOJob):  data size : 5
kio_data::get -> sending end data

kio (KIOJob): FileCopyJob::slotData
kio (KIOJob):  data size : 0        <<<<< this overwrites m_buffer
kio_data::get -> sending finished

kio (KIOJob): FileCopyJob this=0x823db00 ::slotResult(0x824cc38)
kio (KIOJob): FileCopyJob: m_getJob finished
kio (KIOJob): FileCopyJob::slotDataReq
kio (KIOJob):              slotDataReq: returning data size 0    <<<<<<<<< m_buffer is empty
kio (KIOJob): FileCopyJob this=0x823db00 ::slotResult(0x8241270)
kio (KIOJob): FileCopyJob: m_putJob finished

Your pseudo-implementation of suspend doesn't seem to be enough.
If the dataslave isn't in another process, I think you need something like
"if suspended then register somewhere (member var) that resume() should finish the stuff".
