Odd. I'd try a few things:
1) I'd make the keylist use unicode strings since thats what you
   use elsewhere.
2) I'd put a debugging print statement in at the top of the for loop
   to print out the tag values. That will show exactly what tag is set
   to and prove that the loop is being executed and how often
3) change the name of tag in the inner loop since as it is you are
   masking the name in the outer loop which is likely to cause
   strange behaviour.

HTH,
