I think this is a bug in xetex's filename-quoting code. I have been  
able to reproduce the behavior with the current xetex binary from  
TL'09, but not with a local build; this is probably due to differences  
in compiler version, options, or environment that affect the details  
of how memory allocation happens to turn out.

Anyhow, I will check in a fix for what I believe is the underlying  
error, and hope that when Dick rebuilds the binaries, the bug will be  

(committed to TL as xetex 0.9995.2, svn r.15135)
