One thing I didn’t find in my testing and change control was a PHP and XML parsing bug.
Documented in several places – libxml2 2.7.x and greater have a known issue.
One workaround is to force in libxml2 version 2.6.x
Not the most glamorous fix – but opensuse.org has the old libraries from openSUSE 11.0
The better (but more complex) fix is to upgrade PHP to 5.2.9 and libxml2 to 2.7.3
opensuse.org has the correct pieces from openSUSE 11.1
