I've been trying to find and track these down too.  You can use:

M-x semantic-debug-idle-function

or

M-x semantic-debug-idle-work-function

will produce a nice stack.  Thanks.

  [ ... ]

The Emacs Lisp support has both the parsing part, and an "omniscient"
database that queries Emacs' known symbols.  It seems likely that the
include path technique isn't working quite right, but when you eval
the buffer, the omniscient database starts working, and lets symbols
through.

I haven't worked much on Semantic's smart completion for Emacs Lisp
because the existing tools are very good, so I use those.
