Issue #535 duplicate

I just started using gazebo_1.5 which includes the updated SensorManager from pull request #332 and it crashes immediately when gravity gets enabled for Atlas:

Internal Program Error - assertion (eventTime >= common::Time::Zero) failed in void gazebo::sensors::SensorManager::SensorContainer::RunLoop():
/home/thomas/OSRF_REPOS/gazebo/gazebo/sensors/ Time to next sensor update is negative.

This happens by simply running roslaunch atlas_utils atlas.launch and unpausing simulation - it crashes right when the simulator hits second 10, i.e. when gravity gets enabled.
