I recall some issues with the value of the next-hop in the BGP messages in the past. Haven't been around Quagga in recent times, don't know if this is still the case. If possible you might want to catch a BGP packet with tcpdump and verify the value in there makes sense to the other side.
Got bitten by this before and took me ages to figure out the other side was dropping my updates because the next-hop couldn't be resolved.
