This happened because regcomp fails on character ranges in the C.UTF-8 locale. See discussion at http://lists.debian.org/debian-glibc/2011/09/msg00114.html. For now I'm going to back out this eglibc change; C.UTF-8 is used during installation in various places and it's far too risky to make this kind of basic change to its semantics at this point in our release cycle.
