Can't get Boxee 0.9.21.12563 to run on Ubuntu 10.04 64bit

[bigredball]

Hi there,
Hopefully someone can help me.

I'm running a Core2Duo system with stock Intel integrated graphics (I think a GMA 950 chipset but I'm not sure), and I'm running Ubuntu 10.04.

Boxee 0.9.21.12563 (64-bit) won't start at all on my system. There's no obvious failure but the log shows this:

22:46:45 T:140257292556320 M:1451139072 NOTICE: Checking resolution 12

22:46:45 T:140257292556320 M:1451139072 NOTICE: special://masterprofile/sources.xml

And it never gets past that. It happens regardless of whether I use the GUI icon in the Ubuntu application menu or I run /opt/boxee/Boxee from a shell.

I've tried cleanly removing Boxee and starting again, by running:

sudo apt-get purge boxee
sudo apt-get update
sudo apt-get upgrade
sudo rm -rf /opt/boxee/
sudo rm -rf ~/.boxee/

and then rebooting and reinstalling Boxee from the .deb file on the web site. It made no difference.

When I start it, Boxee doesn't seem to be actually doing much - it isn't swallowing up CPU time or anything - it just sits at the stage of "NOTICE: special://masterprofile/sources.xml" and never gets past that. These are the running Boxee-related processes when it's stuck in this loop:

$ ps aux | grep -i boxee
user 5557 0.2 0.7 228332 14616 pts/1 S+ 23:02 0:00 /opt/boxee/Boxee
user 5560 0.0 0.0 9752 860 pts/0 S+ 23:02 0:00 tail -f /tmp/user-boxee.log
user 5598 0.0 0.0 7624 1012 pts/2 S+ 23:02 0:00 grep --color=auto -i boxee

Any ideas?
