tags 660259 = patch pending thanks The key information in the opa config.log is this:

I'm therefore preparing an NMU with the attached patch, based on Samuel's prior investigation, and will upload it to unstable once built. Thanks, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
