Re: trying to disconnect signals from thumbnailsbox

["Jasper St. Pierre" <jstpierre mecheye net>]

We should probably make this a requirement in the future -- it doesn't cost us much to save signal IDs, and allows a lot of extensions to be more flexible.

Why can't gnome-shell classes all store the IDs of the signals they connect to, just like extensions are required to :(

It is so annoying when you can't update your extension because a gnome-shell class is doing something that an extension would get flat-out rejected for (i.e., not storing signal connection IDs and disconnecting when appropriate) :(

Thanks for clarifying - I will try work out how to make a patch (I've been told before; just need to review the notes) and submit a patch/bug report when done.

As the actor is not supposed to be destroyed normally, it's perfectly
possible that we miss disconnecting the signals. Please don't try to
workaround this, but file a bug against gnome-shell (of course
including a patch yourself would be very welcome!)

Thanks,
