Cause

Tasks framework assumes that all the items in the Console have their presentations methods available. At the same time some tasks may not have icons at all (for example Data Connector and Automation). This created an exeception on attempt to show such instances in the preview. Corresponding tasks will not be shown in the preview as a result. No other functional impact will be observed. 

Resolution

Solution at the moment is to ingore the exception keeping in mind that problematic tasks will not be shown in the preview. 
Corresponding bug report has been logged so development is aware of the issue.
