+Summary: crash when serializing array wth 'typed' XmlArrayItem
+
+I get a crash when I set 
+
+[XmlArrayItem (typeof (Daybook.MenuItem))] 
+or 
+[XmlArrayItem ("MenuItem", typeof (Daybook.MenuItem))]
+
+on an ArrayList that is serialized.  It crashes when XmlAttributes calls
+GetCustomAttributes on the ArrayList...
+
+** (Daybook:19090): WARNING **: Cannot load type 'Daybook'
