SQL Sentry processes getting blocked - should I care?

Once a day or so, I'll get "SQL Server Blocking Detected" alerts where SQL Sentry is getting blocked, not any queries from my application. Should I care? I don't see any 'important' queries from my applications getting blocked. Example SQL Sentry blocked query is shown below as spelled out in the email alert.
