Nope, only KConfig was screwed up.
Created a reproduceable testcase, and fixed it in r1023830/r1023836.

It was a fun dialogue between QFile and KConfig... QFile::size() returned 0
because ensureFlushed() failed, and KConfig deduced from that, that
the file _on disk_ was empty and should be deleted (!).
