Just some update:

I called (org-restart-font-lock) function inside my tag search result 
buffer, and I can see a new "Invalid face reference: nil [X times]" 
message is generated in the "*Messages*" buffer, with "X" keeps 
increasing. I have "jit-lock-mode" (Just in time font locking) enabled 
in my emacs config, so I guess that ticking "X" number is from the 
background font locking process.

It seems something is wrong with font locking for tags. But this only 
happens in tag search result buffer. It does not happen in regular 
agenda buffer.

I don't know how to proceed to pin-point this. Can any of you guys also 
reproduce this? Any suggestions?  Thank you.
