I have run into this myself.  The problem for me was that for some 
reason the default launch configuration created was for "gdbserver", 
rather than a locally running GDB.  Try creating your own launch 
configuration manually.

You might want to file a bug on this.  I think with the new contextual 
launching support provided by the Eclipse platform, more people will run 
into this.
