I saw this on a sid system with dpkg 1.19.0.4 installed (piecemeal upgrades). But people might hit it while upgrading from oldstable to the next release? It's a fairly annoying bug because (at least for me) it broke apt and required manual untangling once triggered.
May be a more general problem if this flag is widely used though? -- Peter Eckersley p...@eff.org Distinguished Technology Fellow Tel +1 415 200 7907 Electronic Frontier Foundation
