Fills journalctl with errors #99

Closed ghost closed 5 years ago

ghost commented 5 years ago

On gnome-shell 3.32, Ubuntu 19.04, this extensions fills journalctl with error messages. Representative sample:

== Stack trace for context 0x563349ddc1e0 ==

Object St.BoxLayout (0x56334a67aa80), has been already deallocated — impossible to set any property on it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.

I can reproduce this when I reload the extension (gnome-shell-extension-tool -r shell-volume-mixer@derhofbauer.at). It doesn't happen after a fresh login for me.

This reason seems to be that a lot of signals never get unbound in shell because they didn't think anyone would extend the volume controls.

@georgelemental Does the latest commit to master fix it for you?

If not, could you please provide a complete sample, the one above seems cut off, missing the file and line number.

E.g.

There is a different error now (whenever the volume slider is used):

gnome-shell[6876]: JS ERROR: ReferenceError: GLib is not defined
                   _sliderChanged/this._notifyVolumeChangeId<@resource:///org/gnome/shell/ui/status/volume.js:139:17

This appears to have been fixed now.

aleho commented 5 years ago

Cannot reproduce either and also reloading of extensions has been removed from GNOME because "never actually worked", so 🤷‍♂️.

Thanks for your feedback.
