Fix crash when removing in-process applet and then adding it back (2.26 KB, patch)

Description Alistair Buxton 2013-01-27 03:08:10 UTC 
To reproduce, add the fish applet to the panel, then remove it, then add it again. Other applets also cause the crash.

The following output is produced:

Failed to register object /org/gnome/panel/applet/FishAppletFactory: An object is already exported for the interface org.gnome.panel.applet.AppletFactory at /org/gnome/panel/applet/FishAppletFactory

(gnome-panel:24940): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `PanelAppletFactory'

(gnome-panel:24940): Gtk-CRITICAL **: gtk_accelerator_parse_with_keycode: assertion `accelerator != NULL' failed

** (gnome-panel:24940): WARNING **: Unable to parse mouse modifier '(null)'

Bad use of PanelApplet API: you should not create a PanelApplet object yourself. Please use panel_applet_factory_main() instead.
**
ERROR:panel-applet.c:2087:panel_applet_constructed: code should not be reached
Aborted (core dumped)

The bug only happens when gnome-panel is built with --with-in-process-applets which is what is done in Ubuntu.

I have reproduced this bug with git master to 3.6.0.
