Eclipse: "Run as" does not display the list elements (such as "Run as android application")

This morning I've updated my Ubuntu version and now I can't run my application from eclipse.

The problem is that the list that appears when I click on "Run As" is empty and I can't run anything.

How I can solve this problem?

The only error that I can see, tell me:

An internal error occurred during: "Compute launch button tooltip".
