Ok i managed to reproduce various times on different platforms using the
following instructions. I hope you have time to check it out and give us
feedback what we are doing wrong.. or is it a bug?

* Download and unzip
* If not done already install tomcat, mondrian and libmysql-java (mysql
* If not done already install mysql jdbc driver into tomcat.. for ubuntu
this is:
  cp /usr/share/java/mysql-connector-java.jar /var/lib/tomcat6/lib/
* Import turnover.sql into mysql:
  cat turnover.sql | mysql -u root -p
* Copy (or edit) datasources.xml from testcase to mondrian (be sure to set
the correct database password):
  cp datasources.xml
* Copy turnover cube to mondrian:
  cp turnover.xml
* Restart tomcat or reload datasources
* Run testcase a few times:
  python test_xmla.py

That should give the output:
exception: The Mondrian XML: mondrian.rolap.RolapMemberBase cannot be cast
to mondrian.rolap.RolapCubeMember (code: 00HSBE03)
