Crash in QChangeArbeiter::sceneChangeEventWithLock

I get a crash in QChangeArbeiter::sceneChangeEventWithLock. It looks like QSceneChange instances are being deleted while processed. The crash happens sporadically, but I typically get it after 5-10 minutes of continuous interaction.

Setup

I have a custom QAbstractTextureImage which calls update() to get dataFunctor() reevaluated quite often (e.g. on camera change, which happens rapidly with user interaction).
