LayoutExported.doImportLayouts() throws LocaleException around line 380, when LAR specifies some Locale, that the target Group cannot handle. The is no message in the expcetion, so then when this happens and exception is logged somewhere using standard:

} catch(Exception ex) {
_logger.error(ex)
}

you have no clue from the log which Locale is missing and how you can fix that. Adding some user-friendly message like "Locale X is defined in imported LAR and portal Y does not support this locale" would help a lot.
