Build fails due to illegal characters in path, but offending file isn't specified

[neffo]

Thanks for building this tool, it was doing my head in trying to use mkisofs!

I'm trying to build an iso using the default settings and it's failing with a invalid characters in path error. Unfortunately it's a bit hard to trace it without knowing which file or directory is offending.

Is it possible to list the first invalid file in the dialog box or produce an error log listing them all?

Thanks!

Oh sometimes it does exactly what I said! (But not in all cases?)
