Image_transport tutorials - Crashes upon publishing an image to the topic

edit

Hello!

I've followed the tutorials to get started with image_transport. However, when i start the subscriber, the window created by the subscriber callback (the one titled "view") crashes when i publish an image (by running the subscriber). Also, it doesn't actually show the image from the parameter, but a small part of the desktop instead. Running on kinetic, ubuntu 16.04

Any help would be greatly appreciated!
