Yes, that was it. I was passing some wrong options to the program and
it was exiting without reading it's input. It's solved now. What I'm
doing is running "xsltproc" to convert some XML into HTML with a XSLT.
I guess a better idea would be to do it directly in ruby but ubuntu's
libxslt-ruby1.8 seems to be broken.
