Like in bug 716714, when I clicked Don't Delete in all three windows and then logged out and back in, I got a similar error, but in a different panel applet (the Indicator Applet). The message box's contents now are:
The panel encountered a problem while loading "IndicatorAppletAppmenuFactory::IndicatorAppletAppmenu".
Do you want to delete the applet from your configuration?
And the relevant entry in ~/.xsession-errors says:
** (gnome-panel:6994): WARNING **: Failed to load applet IndicatorAppletAppmenuFactory::IndicatorAppletAppmenu:
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.panel.applet.AppletFactory' on object at path /org/gnome/panel/applet/IndicatorAppletAppmenuFactory
A screenshot of the new variation of the error message (and the desktop without its Indicator Applet) is attached.
After a bit more testing, if I don't see anything to indicate differently, I'll mark this as a duplicate of bug 716714.
