* Merge from Debian unstable. Remaining Ubuntu changes: - 1/rules/utils.mk.in: add some text before listing missing file to make it easier to see from the build log (LP #509249, Debian #565771) - 1/class/gnome.mk.in: Call dh_translations. - test/testsuite_functions: Set NO_PKG_MANGLE so that tests do not fail with pkgstriptranslations installed. (Ubuntu specific) - 1/rules/debhelper.mk.in: Call dh_scour. debian/control.in: Add scour build and binary dependency (build dep for test suite). - Makefile.in, configure, configure.ac, debian/control.in, test/Makefile.am, test/Makefile.in: Drop build dependency on python-support and python-central. Disable distutils pycentral and pysupport tests if the tools are not present (LP #904248).
