Why does gazebo contact sensor topic stops publishing on deleting and respawning the object to whch the contact sensor is atached?

Question

I have a box object model to which I have attached a contact sensor, following this tutorial. On spawning the object in gazebo, initially I get the contact sensor data on the topic /gazebo/default/blue_box1/link/my_contact. However, when I delete this object and re-spawn it, no data is published on this topic, and I just get the following

> Msg Waiting for master Msg Connected
> to gazebo master @
> http://127.0.0.1:11345 Msg Publicized
> address: 192.168.5.30

Please help me in debugging this issue. I have already added the update rate in the sensor, so that may not be the cause. Thanks.

This problem may have been resolved with this pull request. You can try compiling gazebo from source, using the gazebo7 branch, or wait for a new gazebo7 debian release.

Thank you; previously I was using Gazebo 2 which comes with ROS Indigo. I integrated ROS Indigo with Gazebo7, and now this problem seems to be resolved.
