metacity crash while scrolling in youtube

I am wondering how come g_int_hash is shown as calling dcgettext, when g_int_hash is defined as simply

guint
g_int_hash (gconstpointer v)
{
  return *(const gint*) v;
}

Non debug backtraces can be confusing, that's a backtrace with debug packages installed too:

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Also, the issue that you reported is one that should be reproducable with the live environment of the Desktop CD of the development release - Gutsy Gibbon. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

Closing this bug since no more information has been provided, feel free to re open it if you may test it with Gutsy Gibbon.
