Hi! I'm having an issue with Linux 16.04.1 LTS and Cura. I installed the PPA version that is available and it looks like it is going to start just fine. I get a splash screen and then it goes away and nothing happens. If I start it from command line it starts saying CuraEngineBackend.CuraEngineBackend.slic: Starting slice job... and just keeps repeating that forever. Am I missing something? I'd love to be able to run Cura on my laptop. Thanks!
