How to reproduce:

• Inside an XSL of a service (plugin-xxx/pages/services/service.xsl), import another XSL with <xsl:import href="service:xxx://pages/services/service-utils.xsl"/>
• In this XSL, try to display an i18n text without any hardcoded catalogue : <i18n:text i18n:key="I18N_KEY" />
• The message will not be found into the i18n catalogue of the current plugin. It works well if you do the same in the previous XSL (plugin-xxx/pages/services/service.xsl)

According to the error log, it search into the 'messages' catalogue which is not found.
