desktopvideo 9.2 parser error linux

Hi, I work on a Debian 3.2.0-2 64b.
I install successfully the desktopvideo-9.2 package but i got the following
error when I launch the BlackMagic Control Panel by the command line :
"
# BlackmagicControlPanel
"
---->
"
I/O error : No such file or directory
file:///etc/xml/catalog:1: parser error : Document is empty

^
file:///etc/xml/catalog:1: parser error : Start tag expected, '<' not found

^
Segmentation fault
"

What can I do?

Thanks for helping
