If you try the test image that comes with zbar
(http://zbar.sf.net/test/barcode.png) you'll find that without the stride fix
the quality score is 21 and with the stride fix it's 103 (I'm assuming higher
numbers are better).

I've committed this now:

    zbar: use correct stride

    Fixes detection for images with a width that's not a multiple of four.

and also this:

commit 2122c1eb9ad6df534ead1930daff9a17a0817ee8
Author: Tim-Philipp Müller <tim.muller at collabora.co.uk>
Date:   Tue Nov 2 16:32:55 2010 +0000

    zbar: disable cache by default

    Since it breaks still image bar code detection.


Thanks for the patches!
