No, but might have a look at it.

Just before i dashed off, i had another peek at it...
On (!) both machines i did following:
a) ping to the machine at the other side of the bridge simultaneously
B) do a tcpdump at the DOM-0 on the related bridge.

I only saw an arp request, but no answer.
So i manualy pupulated the arp-table at _both_ ends.

Next i saw the ICMP-request of _both_ sides on the bridge, but NO
answer.

Now the intriguing part:
I did a tcp-dump on both virtual machines on the related ethernet
device, i this case eth1 on both sides.
--> on both virtual machine i saw the incoming ICMP-request <--
But, never a reply.

Routing is correct, and all firewalls are down.
On no other network device i could detect a  mis-routed ICMP-reply

Getting stranger and stranger....
Specially as on same devices other bridges are working properly!
