[Evolution] Viewing pdfs inline w/ postscript component

[David Hoover <karma deadmoose com>]

I was wondering if there was any easy way to tell what postscript
component was being used/what it was doing:

I received an attached pdf. If I click, I can "View inline (via
Postscript component)" or "Open in ggv" (well, there's also save, xpdf,
etc. but I don't care about those right now)

If I view it in ggv, it brings up ggv, which can read it just fine.

If I try to view inline, however, the green arrow points down like it
thinks it worked, but nothing is displayed (nor do the scrollbars
appear, so it's not even that it's getting fed back a white rectangle).
I've tried sending myself a couple different pdfs, and get the same
result.

Since it's using the postscript component (which I assume is ggv, since
that's what gnome uses for postscript/pdfs), I tried sending myself a
postscript file, and it's able to render that inline just fine.

Is there any easy way to see what's being run, and if it's giving any
error messages? I'm not getting any from evolution.
