[Qt-creator] Qt Creator 1.3 "Show containing folder" failed xdg-open

[Ed Sutton]

1 - Right-mouse click on a file in the project view.
2 - Select "Show containing folder" 
3 - Displays the following:

"Launching a file explorer failed : Could not find xdg-open to launch the native file explorer."

How do you customize this to work under Red Hat Enterprise Linux 5.x.  I think it uses Nautilus.  I could not find any related options in Qt Creator.

Thanks,

QT Creator 1.3 is looking very nice.
