Crash with no info - Unconfirmed bug

[Glenn Mason <GlennM gui com au>]

So what do we do about bug reports like:
http://bugzilla.gnome.org/show_bug.cgi?id=156450

No trace information (by the way Vincent, how could you interpret the 
last one and reassign it?), pretty much nothing at all other than "PDF 
Viewer crashed".  Can we contact the reporter?  I'm assuming she's just 
clicked on "Yes, inform developers" or equivalent?

Just wondering what the usual process for these kinds of reports are.
