Reproduce:
- For a process definition that contains running instances, create the following report:
	- View: Process Instance : Count
- Group by: Running Date : Year (should be reproducible with any unit, including automatic)
- Visualization: Bar Chart (should be reproducible with any visualization)
- Filter: Running Instances Only
 
Expected:
- The report can be evaluated successfully
Observed:
- Report evaluation fails with this error message:
{
  "errorCode" : "serverError",
  "errorMessage" : "An internal server error occurred.",
  "detailedMessage" : "Text '-Infinity' could not be parsed at index 1",
  "reportDefinition" : null
}
