CSS: Exception raised when using rgba() in a background

[GoogleCodeExporter]

I use the following declarations in a CSS file to set a semi-transparent 
background for certain div's using rgba() in a background property.

div.error {
        background: #FFCEBD;
        background: rgba(255, 206, 189, 0.85) !important; /* #FFCEBD */
        border: 1px solid #F04000;
}

When pisa encounters this the following Exception is raised.

Some time ago Pisa AKA XHTML2PDF has been rereleased under the completely free 
Apache License. Since I personally don't have the time and resources to 
continue the project like before I would kindly ask you to fork the project on 
GitHub and add your patches etc. Maybe someone likes to create a new unified 
version and publish it on PyPI. If you need more help on this get in contact 
with me or write to the XHTML2PDF mailing list. Thank you all very much for 
your effort!
