This patch came from the Ubuntu crash maintainer Stefan Bader. Debian
and Ubuntu both build by default with Werror and the -Wformat-security
option which catches printf and scanf functions where the format
string is not a string literal and there are no format arguments
specified. This patch resolves the issue by explicitly adding the "%s"
format string.
