I'm curious why having an IPV6 address is messing things up.  Is the app 
looking up the IPV6 address from the hostname?  Even that shouldn't be a 

At the top of my /etc/host file where "laptop" is my hostname:
# Do not remove the following line, or various programs
# that require network functionality will fail.	laptop	# Added by NetworkManager	localhost.localdomain	localhost
::1	laptop	localhost6.localdomain6	localhost6

And "ping laptop" gives:
PING laptop ( 56(84) bytes of data.
64 bytes from laptop ( icmp_req=1 ttl=64 time=0.043 ms
64 bytes from laptop ( icmp_req=2 ttl=64 time=0.074 ms

There is also "ping6 laptop":
PING laptop(laptop) 56 data bytes
64 bytes from laptop: icmp_seq=1 ttl=64 time=0.075 ms
64 bytes from laptop: icmp_seq=2 ttl=64 time=0.086 ms

There is nothing there that should break any application unless it's 
doing something strange or wrong.
