Check that MODENAME-mode is fboundp before calling it, files.el 2010-04-15 Aidan Kehoe <kehoea@parhasard.net> * 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!
