+	* files.el (hack-local-variables-prop-line)
+	(hack-one-local-variable):
+	Only attempt to call MODENAME-mode on encountering a
+	-*-MODENAME-*- line if the corresponding symbol has a function
+	binding, avoiding an error if, for example, opening a log file
+	with XLFDs and wild cards. Thanks for the bug report, Henrique
+	Martins!
