warning: older versions of msgfmt will give an error on this
compiz.merge-plugin-freewins/po/uk.po:8: header field `Project-Id-Version' still has the initial default value

compiz.merge-plugin-freewins/build/compizconfig/compizconfig-python/compizconfig.c:631:46: warning: ‘__pyx_f_12compizconfig_ListToStringList’ defined but not used [-Wunused-function]
I will investigate this.
