Nautilus wiles out for seconds when loading large directories

[sem]

To create the bug
1. Browse a large directory
2. Select some folder a few hundred subdirectories down
3. Enter subdirectory
4. Go back to the parent directory

Instead of seeing the parent directory right away, nautilus wiles out for a good 20+ seconds. It appears that it could be 'scrolling down' from the top of the directory to the current position?

I don't know if this is an upstream bug or not, but apport makes it easy to collect all information, so I'm filing it here first.

See the .gif for an example.
