Comment #1 on issue 991 by pekka.klarck: xPath count is not working for
div/table/tr etc (non-form field)

First of all, this issue tracker is for Robot Framework itself. SeleniumLibrary has its own tracker and issues related to it should be submitted there. Based on your description the actual bug seems to be in Selenium itself, though, so this probably couldn't be fixed in SeleniumLibrary.
