Thanks for your reply.

Perhaps this is a Ghostscript problem. When I run the Ghostscript command, I'm 
met with the rather unhelpful error: 'GPL Ghostscript 9.01: Unrecoverable error, 
exit code 1 (occurs whether or not I remove the -q)'. 

Interestingly, if I remove the final argument (in this case, capturevasarely.ps) 
the Ghostscript command executes, placing a file (appears to be xml) in the 
temporary directory. However, I'm not sure what to do with this result.
