I guess latest xserver-xorg-core and xserver-xorg-video-intel won't change
anything here. It looks like a mesa problem to me, something like a GPU
lockup. SecondLife uses OpenGL/DRI, right?
Being easy to reproduce is a very good point here.
Would you mind reporting this bug upstream at bugzilla.freedesktop.org
product mesa component drivers/dri/i915 ? If you can't, I'll do it.
