Why SQL Server 2008 Reporting Services keep crashing when connecting to remote database server instance?

Background

I successfully setting up a database for SQL Server Reporting Services in Windows Server 2008 R2 using Reporting Services Configuration Manager with "Create a new report server database" option. The next step I want to do is test connecting the created database remotely via a client machine running Windows 7 SP1.

Problem Statement

I installed same version of SQL Server 2008 R2 into client machine & begin connecting to remote server instance. Using "Database" => "Change Database" => "Choose an existing report server database" shows this screen, all seems to be working fine until this point:

However whenever I trying to use "Test Connection" or advance to next step (expecting to select Report Server Database), it suddenly crashed with crash report given below:

Message:
  SQL Server 2008 Reporting Services Configuration Manage has stopped working

A further look into Event Viewer => Windows Logs => Application shows this error log:

How can I get rid of this error and connect to remote server instance properly?
