From: Kyle McMartin <k...@redhat.com> Commit 77c1ff3982c6b36961725dd19e872a1c07df7f3b fixed the userspace pointer dereference, but introduced another bug pointed out by Eugene Teo in RH bug #564264. Instead of comparing the point we were at in the string, we instead compared the beginning of the string to "default".
