  Argh, well I went with the full GDB thing, which helped find some 
of the problems but not that one specifically.
  Patch applied, but I'm still seeing an error:

  With the debugging stderr calls still left. it seems virConnectOpenAuth()
does not work, and it seems something happens within the callback from
native to the Java authentication routine.
  Also seems the exception wrappers don't properly zeroe some of the strings
which need some investigation too.
  Would that be a JVM or 64bits specific issue ?  1964848024 is suspiciously
large and 0x751d3398 could well be a valid pointed, but casted to the wrong
place.

  Oops, yes :-)

   Heh, enjoy your vacations, and thanks for the quick feedback !

  Well it made me learn more about the code :-)
