another nautilus stack trace

[Darin Adler <darin eazel com>]

I was just talking to Nat about this bug in IRC, and he asked me to post the
stack trace to the list (something I otherwise normally wouldn't do). You
can reproduce this by starting nautilus, clicking on a text file (so you are
viewing it with the plain text component), and then pressing the up button.

I think this is a bug in bonobo code, not the plain text component, because
am pretty sure I saw it with the HTML component too at one point.

Looks like a double-destroy problem of some kind.
