Comment 2 for bug 223560

The error is cause by the i18n part in buildout.cfg_tmpl

# this section named so that the i18n scripts are called bin/i18n...
[i18n]
recipe = z3c.recipe.i18n:i18n
packages = ${package}
eggs = ${package}
domain = ${package}
output = src/${package}/locales
zcml =

package names are mangled by paste.script (removes any charater but 'a-zA-Z0-9_')
the i18n part schould replace ${package} by ${egg}
