oops, that was the GTK_ Version number.  My emacs is 24.3.1.

Yes and Yes.  At least, I swear it worked in my hands yesterday, but today the answer is No and No.  !!  I can't explain what has changed.

In my hands, both the #+CAPTION and the #+att_latex as you place them are deleted upon source block evaluation. 

Are you sure your placement works for you?

Summary: In my hands today, there is no placement of them that both survives source block re-evaluation and works.  And, they can both be placed immediately above or below the #+RESULTS: line and are respected on export.

(However, another funny interaction, the caption of the longtable has multiple entries, one for each page, in my #+LATEX: \listoftables )

Hmmmm....
