[XeTeX] Small bug found in xdv2pdf

[Jonathan Kew]

Hi Brian,

Many thanks; I'll apply this to the source.

Just wondering, can you point me to a particular font that caused a  
crash here? I can see that it's a possibility, so it's necessary to  
check, but would be interested to see an example that triggers it.
