Comment 12 for bug 535385

Yes, but how is the user supposed to know this? I'm on Natty now, and on the export window I get "You are missing libmp3lame". There is a read more link but it's broken. If libavformat-extra is not listed as a dependency, at least it should be made available for install from the export window itself, pretty much how totem or other apps download the necessary pckgs if you allow them.

And even if this can't be done, the message should explicitly say "Install libavformat-extra".
