--- Comment #6 from David Edmundson <k...@davidedmundson.co.uk> --- We have a SourceModel that inherits from AbastractModel AbastractModel inherits from both QObject and Ref When we call the destructor of Ref, that kills the Pulseaudio::context that emits that the default source has changed during it's teardown. Because the QObject destructor hasn't run yet, our signals are still attached; however they refer to data from SourceModel which we've already run the destructor on - hence crash. Will fix. -- You are receiving this mail because: You are watching all bug changes.
