Gajim-to-itself file transfer fails if I don't change the file name
If I have two accounts (with the same, local XMPP server, though that probably doesn't matter) in the same Gajim install both connected, and I try to file transfer from one to the other, it works if I change the filename before saving, but if I don't it just hangs and I see an error about out-of-order or unexpected stanzas in the XML console.
XML logs attached.
