Description Allison Karlitskaya (desrt) 2005-03-13 18:30:22 UTC

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---
(no debugging symbols found)

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.

Thanks for the bug report. Unfortunately, that stack trace is not very useful in
determining the cause of the crash. Please make sure that the package was
compiled with debugging symbols and see
http://bugzilla.gnome.org/getting-traces.cgi for more information about useful
stack traces.

Comment 2 Allison Karlitskaya (desrt) 2005-05-27 23:39:41 UTC

This doesn't happen anymore.
