Hi, Antoine.  Was there a "this hand"?  ;)

So I guess this is a packaging problem, either with xpra or libav?

I have two libavcodec libraries installed:

libavcodec53:amd64
libavcodec54:amd64

The package dependency is for libavcodec53.  Could there be an issue
with which version is being linked to?

Do you have any suggestions how I can help debug what's going on?
