This is partially related to ticket 300 due to the shielding part. When I initially saw that StatusShield.lua was the file with the error, I first attempted to look in the configuration for the spells under status/health&heals/shields. Three checkboxes had checks next to them but no spell name (Divine aegis, Sacred Shield, and Savage Defense). I've been leveling a bear druid, and remember that Savage Defense is no longer a shield, but a heal. Looking at the spell IDs of Divine aegis and Sacred shield from line 13 and on, apparently the spellIDs for these were changed. Here is a list of the changes, with current addition you may want to add as well:

Divine Aegis was changed from 47509 to 47515
Spirit Shell is 114908 (the acutal absorb, not the buff to activate Spirit Shell which is 109964)
Sacred Shield was changed from 85285 to 65148(the acutal absorb, not the buff to activate Sacred Shield which is 20925)

Changing these spellID appear to make everything work again before 5.0.4 was released.
