In trunk, the reproduction steps should be modified to:

1) Start a TRUNK bundle and login the portal.
2) Go to Control Panel and create a new Structure (and a Template) in the Web Content portlet for the default Liferay site.
3) Stop the bundle and add the following properties to the portal-ext.properties file.
company.default.locale=en_AU
locales=en_AU,en_US
locales.enabled=en_AU,en_US
4) Start the bundle and make sure the Default Language of the portal has been configured to English (Australia) in Control Panel.
5) Perform step 2 again and create another Structure (and a Template) in the Web Content portlet for the default Liferay site.
6) Switch the Default Language of the portal back to English (United States) and export the Liferay site.
7) Create a new blank site, configure its default language to a non-default one, say English (Australia) and then import the exported LAR file to that site.

Or another reproduced steps:
1. Set locales.enabled=ca_ES,zh_CN,nl_NL,en_US,fi_FI,fr_FR,de_DE,iw_IL,hu_HU,ja_JP,pt_BR,es_ES,en_AU in portal-ext.properties.
2. Start Portal, go to Control Panel and create a new Structure (and a Template) in the Web Content portlet for the default Liferay site(en_US). And export the Web Content portlet "webcontent.lar".
3. Go to Portal Settings, change Default Language from "en_US" to "en_AU".
4. Create one blank site "Blank Site" and then go to "Blank Site" >Site Setting>Display Settings, define a custom default language "nl_NL" for this site.
5. Go to "Blank Site"->Web Content, import the "webcontent.lar".

Then you will face with the error message of:
