Description of problem:
If you print an email whose attachment is displayed, the printout will only
print that there _was_ an attachment, not what was actually showing up.

Version-Release number of selected component (if applicable):
evolution-2.0.2-25

How reproducible:
Always

Steps to Reproduce:
1. Open an email with a meeting invitation attachment
2 [details]. The meeting invite is displayed.
3. Print the message
  
Actual results:
The printout just gives the headers and "iCalendar file attachment
(calendar.ics)", rather than the actual displayed invite.

Expected results:
It should print what is shown.

Additional info:
Not sure if there is an option to fix this, but the default behavior ought to be
to print what is visible.

I do not expect that this is x86_64-only, but since I'm seeing it on my x86_64,
I will label it as such. I also do not expect that it's RHEL4-only.
