DVL plugin causes Gazebo to crash when deleting UUV model

[steenstral]

Hi,

I encountered a problem while using the DVL sensor plugin. When I try to delete a UUV model (with a mounted DVL sensor) from the world, Gazebo crashes giving the following error message:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >' what(): boost: mutex lock failed in pthread_mutex_lock: Invalid argument Aborted (core dumped) [gazebo-2] process has died [pid 7756, exit code 134, cmd /opt/ros/kinetic/lib/gazebo_ros/gzserver --verbose -e ode worlds/ocean_waves.world __name:=gazebo __log:=/home/piet/.ros/log/f6aa0a80-1fab-11e9-8f4d-503eaa6587e4/gazebo-2.log]. log file: /home/piet/.ros/log/f6aa0a80-1fab-11e9-8f4d-503eaa6587e4/gazebo-2*.log

This only happens with the DVL sensor plugin and is not related to the vehicle I'm using, as it happens both with the LAUV model and the Rexrov model (from the tutorials). I'm using Gazebo version 7.0.0. Is there a way to fix this?

Thanks in advance!
