If we're talking about the same thing, ie: "The application File Manager has closed unexpectedly" it appears that using Update Manager only causes that report if updates are available and actually applied.
But I found another way to reproduce it. Open synaptic, search for an app (I chose 'xfce4-screenshooter' and then deselected xfce-panel), install the app, and afterwards I get the same error report. Screenshot attached.
