That is really odd. Your memory dump actually showed it either failed to read the file, or that it read a blank file. It shouldn't have mattered at all about the [i]:[/i]. I wonder whether saving the file was what fixed it... I can't quite understand how the italics could have affected it anyway - they are simply used as a string, and not interpreted in any way.
Anyway, thanks for fixing it and letting me know. If you run into problems, you could always add the italic tags back, and I reacon that it will probably continue to work.
