Following my previous posts on the issue, if you were using my Debian packages to have Second Life in Debian, please change and start using the packages (aptitude install slviewer) on this repositories:
deb http://cornelius.demon.co.uk/apt/ unstable main
deb-src http://cornelius.demon.co.uk/apt/ unstable main
deb http://apt.byteme.org.uk/apt/ unstable main
deb-src http://apt.byteme.org.uk/apt/ unstable main
