radosgw crashes when uploading files using swift

Deployment:

Single server running MON and OSD
Single server running RADOS Gateway
Single server running Openstack Keystone

The Gateway is configured to use Keystone for authentication; I'm using the python-swiftclient package to upload files into swift.

Authentication is working fine; however when I try to upload larger files with content (and by larger I mean 20M - so not really large) the radosgw process segfaults
