1. Given configuration folder /path/to/config containing OspSystemStructure_test.xml

2. Start cosim-demo-app and specify configuration as: /path/to/config/OspSystemStructure_text.xml

3. Start simulation

4. Click 'Reset'

5. cosim-demo-app crashes

6. Rename OspSystemStructure_test.xml to OspSystemStructure.xml
