If you move a page without leaving behind a redirect, and you move the talk page simultaneously, the talk page leaves behind a redirect. The setting to not leave a redirect should apply to talk pages and subpages which are moved simultaneously.
I tried exactly that on iuwiki with my user page: http://iu.wikipedia.org/w/index.php?title=Special%3ALog&type=move&user=&page=&year=2008&month=11 (Move log), and http://iu.wikipedia.org/w/index.php?title=Special%3ALog&type=delete&user=&page=&year=2008&month=11 (Delete log). BR, Th.
Couldn't recreate in 1.18svn, so I'm going to assume this was fixed at some point and mark it closed as such. I did try to find the exact revision but to no avail (must have been a side-effect of a tangentially-related commit). Anyway, fixed.
