I just added a SelectOutput filter that lets you choose among the 
available outputs of a given source/filter.  This is a simple solution 
that should let you choose which block to view.  Here is an example from 
the data that Francesco reported here:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=478359

mayavi2 -p tiny.xyz -q tiny.q -f SelectOutput -m Outline -m Surface

Click on the SelectOutput and select the output index of the data to 
use.  You should be able to change the block.  Add any number of these 
filters to the reader to choose whichever you want.  The more complex 
feature request that Francesco requested is more work than I have time 
for now.

I've checked this into the 2.1.2 branch in addition to trunk.
