Public bug reported:
I am writing a Gnome Shell extension which uses gi.PackageKitGlib.
The following example code takes place inside a function and when
pkpackages goes out of scope, it would eventually cause Gnome Shell to
crash. The error in .xsession-errors says, "Window manager warning: Log
level 6: Finalizing proxy for an already freed object of type:
PackageKitGlib.Package".
If I keep the instance of the object persistent, then it does not crash.
Example code of extension.js:
/************************/
const Pk = imports.gi.PackageKitGlib;
function getupdatespk() {
let pkclient = new Pk.Client();
let pkresult = pkclient.get_updates(Pk.PK_FILTER_ENUM_INSTALLED, null,
function(){});
let pkpackages = pkresult.get_package_array();
};
function init() {
};
function enable() {
getupdatespk();
};
function disable() {
};
/************************/
Error in ~/.xsession-errors:
Window manager warning: Log level 6: Finalizing proxy for an already freed
object of type: PackageKitGlib.Package
** Message: applet now removed from the notification area
