Created Issue: Object reference error on Effective Permissions Report [11419]

I'm running version 3.6.0.15 on Windows 7 x64. I have an app store setup, with operations, tasks, roles, and application groups. My web apps run correctly using the authorization provider. However, when I try to run the Effective Permissions report I always get an error. I've tried from the web interface (see screenshot) and from the snap-in console. I've included the event log message below:

<b>Error Caught in Application_Error event</b><hr><br><br><b>Error in: </b>http://localhost/NetSqlAzMan-WebConsole/rptEffectivePermissions.aspx<br><b>Error Message: </b>Exception of type 'System.Web.HttpUnhandledException' was thrown.<br><b>Stack Trace:</b><br>System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---&gt; System.NullReferenceException: Object reference not set to an instance of an object.
