I am running Fuerte and I am getting the following error when launching rxbag with the --record option. It works fine when launching without the --record option (using an existing .bag file). Other rx utilities work fine (rxconsole, rxgraph). Recording using rosbag also works fine.

~/ros_workspace$ rxbag --record --all

Any ideas?

Thanks! Vassilis
