Description of problem: Pavucontrol hangs when streams finished while dragging slider of its volume control, outputting the following to the standard error output: (pavucontrol:12950): Gtk-CRITICAL **: gtk_widget_event: assertion `WIDGET_REALIZED_FOR_EVENT (widget, event)' failed (pavucontrol:12950): Gtk-CRITICAL **: gtk_widget_event: assertion `WIDGET_REALIZED_FOR_EVENT (widget, event)' failed ... Version-Release number of selected component (if applicable): pavucontrol-0.9.4-3.fc6 How reproducible: Always Steps to Reproduce: 1. launch pavucontrol 2. play a stream 3. drag stream's volume control's slider until the stream finishes Additional info: I reproduced it having pulseaudio ALSA virtual device configured and doing something like: while (aplay -Dpulse /usr/share/sounds/alsa/Front_Right.wav); do :; done Do that and play with pavucontrol's volume control slider.
This sounds more like a gtk bug to me: when we destroy the slider that belongs to the stream gtk doesn't seem to be able to fix the event routing for it. Reassigning.
