I have written a simple node that captures the videostream of an USB webcam using OpenCV and publishes the frames. So far, it always worked to display the frames in the rqt_image_view plugin.
However, when I remove the `~/.config/ros.org/rqt_gui.ini` file and rebuild the catkin workspace, the plugin crashes with a segfault as soon as I select the frame topic. Strange enough, if I revert to the old `rqt_gui.ini` file (lucky that I made a copy of before removing it), the image_view plugin works again. I suspect that this is a problem of OpenCV 2 and 3, but I can not infer the relation to the `rqt_gui.ini` file.
Does anybody have an idea, what is going on here?
