Quote from an upstream (bugzilla.gnome.org) comment: https://bugzilla.gnome.org/show_bug.cgi?id=721369
GLib recently started throwing a warning when g_source_remove() is passed garbage (as per warning). Your applications have probably been broken for a while, and there's no telling what could actually have happened in the past when g_source_remove() would happily close any random source because the programmer got the wrong argument to g_source_remove(). So if true, it looks like this should be reasssigned either to Glib, or to all the affected applications. The problem isn't just the error (log pollution). When the error occurs, I see ssh sessions actually hang when console-kit-daemon prints the error. This is a regression in 14.04 vs 13.10. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1264368 Title: GLib-CRITICAL **: Source ID was not found when attempting to remove it - warning when leaving Network menu of g-c-c Status in GNOME Control Center: Incomplete Status in “gnome-control-center” package in Ubuntu: Triaged Bug description: Steps to recreate: 1.
