+Summary: DataSet.ReadXml table string allocation error
+
+Description of Problem:
+
+I want to display some data coming from an XML file into an ASP Datagrid.
+However, when I call System.Data.DataSet.ReadXml(), an exception occur.
+
+Steps to reproduce the problem:
+1. Get the attached archive, and decompress it
+2. (Optionnal) Compile Bug.cs
+3. Run "mono Bug.exe"
+
+Actual Results:
+
+Unhandled Exception: System.Data.DataException: The table string is already
+allocated as another table's child table.

+in <0x0003b> System.Data.DataSet:ReadXml (System.IO.TextReader)
+in <0x000fd> Bug:Main ()
+
+Expected Results:
+
+No exception.
+
+How often does this happen? 
+
+Always, with Mono 1.0.2 and Mono 1.1.1.
+
+Additional Information:
+
+The problem will only occur if the XML file contains at least two complex
+items. For exemple, this XML file will not produce any problem :
+
+<?xml version="1.0" encoding="utf-16"?>
+<ArrayOfUserEntry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+xmlns:xsd="http://www.w3.org/2001/XMLSchema">
+  <UserEntry>
+    <login>test</login>
+    <emails>
+      <string>me@there.com</string>
+      <string>this.is.me@there.com</string>
+    </emails>
+  </UserEntry>
+</ArrayOfUserEntry>
+
+However, this one will make the exception occur :
+
+<?xml version="1.0" encoding="utf-16"?>
+<ArrayOfUserEntry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+xmlns:xsd="http://www.w3.org/2001/XMLSchema">
+  <UserEntry>
+    <login>test</login>
+    <emails>
+      <string>me@there.com</string>
+      <string>this.is.me@there.com</string>
+    </emails>
+    <permissions>
+      <string>manage_vacation</string>
+      <string>manage_timesheet</string>
+    </permissions>
+  </UserEntry>
+</ArrayOfUserEntry>
