Description of problem: I have a volume that has a snapshot that depends on it. As expected, I can not delete it. When I click the "Delete Volume" button in Horizon for this volume, I get an appropriate error dialog that tells me why it can not be deleted. However, this action leaves a large traceback in /var/log/httpd/error_log. I don't think it should be in the error log. It's an expected type of error that should be handled gracefully.

For me, this issue is fixed on grizzly.
Verified NVR: python-django-horizon-2013.1.1-1.el6ost.noarch Tested via horizon: 1. Created a Volume. 2. Created a Volume Snapshot. 3. Tried to delete the Volume. The traceback is now replaced with: [Wed May 22 07:17:17 2013] [error] \x1b[31;1mRecoverable error: Invalid volume: Volume still has 1 dependent snapshots (HTTP 400) (Request-ID: req-91c1dc42-7058-4cd7-bd52-7adb23964e10)\x1b[0m
