Description
I have a Qt Quick app and it randomly crashes when putting the app in the background. Here is the crash log.

According to http://stackoverflow.com/questions/14468888/gpus-returnnotpermittedkillclient-error-thrown-with-mkmapview-when-app-is-backgr gpus_ReturnNotPermittedKillClient gets thrown when OpenGL actions are triggered while an app is backgrounded. I don't think I'm doing any OpenGL actions myself, the app features a ListView loading images from the web and a busy indicator. I tried to reproduce in a minimal case without success so far... Any guidance appreciated.
