Bug Description

Binary package hint: gnome-power-manager

The battery status notification icon in gnome-power-manager seems to be crashing. Every time it does it adds empty space to the notification are to the point where it fills the whole panel. Here's the error message that gets repeated in .xsession-errors:

(gnome-power-manager:1586): GLib-GObject-WARNING **: invalid cast from `GtkStatusIcon' to `GtkWidget'

(gnome-power-manager:1586): Gtk-CRITICAL **: gtk_widget_hide: assertion `GTK_IS_WIDGET (widget)' failed

I reproduced the bug consistently by running it in g-p-m in gdb with:

CK_FORK="no" G_DEBUG="fatal_criticals" libtool --mode=execute gdb gnome-power-manager

Starting with my laptop connected to AC power I unplugged and got the immediate warning and this stack trace:

Seems like the real bug is in frame #2 and actually inside libappindicator. libappindicator/app-indicator.c:898 does:

gtk_widget_hide(GTK_WIDGET(status_icon));

where status_icon is a GtkStatusIcon, something that according to the manual descends directly from GObject and that is why the GTK_IS_WIDGET assertion then fails.

The bus is thus in libappindicator and is the same as #530429.

It seems like this commit fixes the bug:

http://bazaar.launchpad.net/~indicator-applet-developers/indicator-application/trunk/revision/96.1.1?remember=96.1.1

This is in trunk so version 0.0.15 of libappindicator0 should fix the bug.
