Ok. On the box with the bridge, su to root and start a tcpdump session:

# tcpdump -n -i bridge0

...and then, on 192.168.0.4, ping 192.168.0.5

After the ping is done (whether it works or not), stop the tcpdump and
email the output to the list if you can. If you can't email it, at least
type out the IP addresses captured, and the direction the data is
attempting to flow eg:

208.70.104.210.22 > 208.70.104.100.50885
208.70.104.100.50885 > 208.70.104.210.22
arp who-has 208.70.104.206 tell 208.70.104.193

etc.
