Bash had removed a Requires(post) on ncurses, which cased an install loop to not get the right info (bash calls sh (or bash) in %post, which needs the ncurses libs there). I added back the Requires(post) on ncurses-libs to resolve this issue. I verified that the build worked by reproducing the problem (mock init i386 would cause it) and then adding the updated bash to a repo and doing the same thing. With the fixed bash there is no %post error.

bash-3.2-29.fc10 is the build, and I give it a +1
