Pinning Media Center to Windows 7 Taskbar causes Explorer to crash

When I right-click the Windows Media Center icon and choose "Pin to Taskbar", Explorer crashes. Anyone else experiencing this?

Edit: Here's the info from the error posted to the event log:

It works on my machine - Windows 7 Ultimate 64 bit.

You could try running diagnostic tests on the RAM using the Memory tester that comes with Windows - it might be a memory problem. You can get to this by booting from the Windows DVD and the Repair option.
