Distribution/Version: hoary

i have a specific mpeg file that when i right click -> properties nautilus
quits.  i don't get the "this application has unexpectedly quit" dialog.  it
just exits.

here's what gdb says when i invoke nautilus from the console and open the
properties on the file:

(gdb) r
[blah blah blah]
---Type <return> to continue, or q <return> to quit---

anyway.  i've uploaded the file here:  http://manic.desrt.ca/carwreck.mpg

it's slightly distasteful, but definitely work-safe.  feel free to attach a copy
to the bug report if this is going to take a long time to fix and you're afraid
that the file might go missing (i wasn't sure if i should attach a 1.5meg file
to a report or not).

i'm using ubuntu hoary preview up to date as of now.

according to this spiffy synaptic thing, that means:
libgstreamer0.8-0.8.9-1ubuntu2
gstreamer0.8-[various plugins]-0.8.8-0ubuntu1

cheers.
