Bit yes, bit no. See below.

To your problem there are two approaches:
- bind explicitly to :: and to 0.0.0.0 (so an ipv4 and a separate ipv6 bind)
- change your sysctl.conf to contain: "net.ipv6.bindv6only = 0"

If you opt for the latter don't forget to reload sysctl settings or change that option using the 'sysctl' command. No reboot necessary!

This is because the latter setting changed in debian squeeze a while ago. It now defaults to a setting that prevents listening for ipv6 and ipv4 on the same bind. (This also used to break java)
