dogtail-devel Stricter error handling committed to CVS

[David Malcolm <dmalcolm redhat com>]

I just committed the patches to pyspi and dogtail for:
http://bugzilla.gnome.org/show_bug.cgi?id=318135

so that now, any kind of low-level error in pyspi (e.g. the application
under test just died) should propagate through to a Python exception
being raised in your dogtail script - I also added a unit test for this.

So Dogtail should now be much stricter and I believe much more correct.
I believe that the only failures that should occur from this will be
true failures - I ran the unit tests before committing and all was well
- but there's a possibility that I've introduced false positives in
error detection from this, so please email this list if you're seeing
such things.

Hope this helps
Dave
