It's Content-Type: application/pdf; so if I follow what you are saying
the association to "Document Viewer" was not working for some reason.

It appears to have been something funky in the association handling, as
this is not a generic octet stream.
I say "have been" and "was not" because I had problems with DVD/CD
writing crashing X and logging me out (thus making a lot of coasters) if
Desktop Effects were enabled (ati based system).
After I removed my .gconf* directories last night to get rid of the last
of the compiz effects, the same attachment/email is now working.
