I noticed a small glitch on the actionlib tutorial page for writing a 
Python server:

http://www.ros.org/wiki/actionlib_tutorials/Tutorials/Writing%20a%20Simple%20Action%20Server%20using%20the%20Execute%20Callback%20%28Python%29

The code breakdown for lines 40-45 is interrupted with the error:

ERROR: unindent does not match any outer indentation level

I saw that the CodeRef for that block was for lines 40-42 so I changed 
it to 40-45 but that did not fix the error so at this point I need to 
punt.  (The Python indentation looks fine to my eye but maybe someone 
else can catch it.)
