 The reason for this is that during development you'd usually want your views to still render even though a translation is missing.
 
-In other contexts you might want to change this behaviour, though. E.g. the default exception handling does not allow to catch missing translations during automated tests easily. For this purpose a different exception handler can be specified. The specified exception handler must be a method on the I18n module:
+In other contexts you might want to change this behaviour, though. E.g. the default exception handling does not allow to catch missing translations during automated tests easily. For this purpose a different exception handler can be specified. The specified exception handler must be a method on the I18n module or a class with +#call+ method:
 
 <ruby>
 module I18n
-  def self.just_raise_that_exception(*args)
-    raise args.first
+  class JustRaiseHandler < ExceptionHandler
+    def call(exception, locale, key, options)
+      if exception.is_a?(MissingTranslation)
+        raise exception.to_exception
+      else
+        super
+      end
+    end
   end
 end
 
-I18n.exception_handler = :just_raise_that_exception
+I18n.exception_handler = I18n::JustRaiseHandler.new
 </ruby>
 
-This would re-raise all caught exceptions including +MissingTranslationData+.
+This would re-raise only the +MissingTranslationData+ exception, passing all other input to the default exception handler.
+
+However, if you are using +I18n::Backend::Pluralization+ this handler will also raise +I18n::MissingTranslationData: translation missing: en.i18n.plural.rule+ exception that should normally be ignored to fall back to the default pluralization rule for English locale. To avoid this you may use additional check for translation key:
+
+<ruby>
+if exception.is_a?(MissingTranslation) && key.to_s != 'i18n.plural.rule'
+  raise exception.to_exception
+else
+  super
+end
+</ruby>
 
 Another example where the default behaviour is less desirable is the Rails TranslationHelper which provides the method +#t+ (as well as +#translate+). When a +MissingTranslationData+ exception occurs in this context, the helper wraps the message into a span with the CSS class +translation_missing+.
