You know I was a bit puzzled by this because I distinctly
remembered creating a temporary directory and putting temp
files in it when I last touched that code. I looked just
now and the temp directory code is still there, see 
DataDirectProcessor::CreateTempDirectory().

DataDirectProcessor::DDPost() looks like it's an exception
and it doesn't event make any sense. We write out the data
to this file from a QByteArray and then immediately read it
back out of the file into a new QByteArray. It also doesn't
use m_tmpDir like the other DataDirect stuff that touches
the file system.

I'll assign that ticket to myself and take a look at it soon.
