If you help me to do some testing I'd be happy to help fix this.  This means
that Wine is dropping the packet with the BPF that we're using to screen for
interface-specific packets.  Would it be possible for you to capture the packet
meant for Wine with Wireshark and send me the packet?  Also, what version of
Wine are you running?
