In my personal case, it happens every now and then without any external 
activity, and definetly without any manual deleting (may be it's related 
to automatic filtering?)

I don't think so. Just right click on any folder in the folder pane, and 
in spanish there is a "Borrar duplicados" option. But I have installed a 
"Remove Duplicate Messages (Alternate)" extension, maybe this option 
comes from this.

Aaaaaaagur.
