mr. Ed: Copying-and-pasting with Ctrl-C Ctrl-V (technical term "CLIPBOARD") is completely separate to copying-and-pasting using mouse select and middle-click paste (technical term "PRIMARY").
This bug is that left-click in a window is clearing the selection *and* clearing PRIMARY, rather than just clearing the selection. My original belief on the times that I accidental did this was that I'd just done something wrong, but it does indeed appear to be the application/Gtk+ widgets that are broken in this respect.
