Include assertion messages in bug reports

[Cosimo Cecchi <cosimoc gnome org>]

Hi everyone,

I made a patch for bug 350221 [1], which allows bug-buddy to log all the
critical and fatal warnings emitted by an application, and print them in
the report if the application crashes. I think this is an useful feature
for better identifying duplicates and it should also help debugging.

I have two doubts to clear before committing the patch to trunk:
- what is the right placement inside the report for this information?
right now it's placed just above the stacktrace.
- is .xsession-errors still useful if we're tracking messages ourselves?
Usually I only look for this kind of assertions there.

Comments welcome!
