Could someone please enlighten me as to the correct method of resolving this error?
My LyX file references a number of fonts however I have not been able to successfully convert to PDF for some time due to various reasons. I have solved them all bar this one, and am quite stumped. I don't recall changing any fonts since the last time I successfully output to PDF (albeit back on 1.6, this is now 2.0rc2). Other than going in to the LyX file manually and replacing all font references with a 'known good' one, is there any way to know which line this error actually references? As error messages go, this one seems pretty opaque.
