Have you checked to verify the data is right? this error is because the property is null.. has no data or has not been initalized.
try to inialize your components on creation.
have you tried the suggested work-around in that bug report eg don't set the axis title property? If you have tried this and the problem persists, chances are it is a different issue.
If it is this bug, then the report says it's fixed at a particular version number so presumably SDK downloads from after that time will be OK.
