Not able to open Printer manager & applet.

Not able to open printer manager "Printing" application
Not even the first window is being shown, neither the printer applet is visible.

The same used to work with Ubuntu Maverick but this stopped working after updating to Ubuntu Natty.

When i try to run it from command line the following is the log that i am noticing
