This code is being executed for a file that doesn't have the variable 
defined - i.e. stage.txt.

Is this in your template? If so it will be executed for every file.

You could get round this by putting something like the following 
*before* the code:

try:
    localnavbar
except NameError:
    localnavbar = 'no'
