Further investigation (see bug 708118, now duplicate and gnome#614800 (https://bugzilla.gnome.org/show_bug.cgi?id=614800)) shows that this appears to be an issue in libappindicator: looks like it unrefs themed_icon too early or something (or too often, called by the theme/icon changed signals).
There are two possible fixes: getting rid of the g_object_unref of themed_icon in status_icon_changes() callback, or making the callback use icon names instead of a generated GIcon. ** Bug watch added: GNOME Bug Tracker #614800 https://bugzilla.gnome.org/show_bug.cgi?id=614800 ** Package changed: network-manager-applet (Ubuntu) => libappindicator (Ubuntu) ** Changed in: libappindicator (Ubuntu) Importance: Medium => High ** Changed in: libappindicator (Ubuntu) Status: New => Triaged ** Branch linked: lp:~mathieu-tl/libappindicator/lp708118 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/729150 Title: nm-applet crashed with SIGSEGV -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
