Hello,

Yes, it fails. -debug gives me this log:

runPlugin: ij.plugin.DragAndDrop
actionPerformed: time=1266940789402,
java.awt.event.ActionEvent[ACTION_PERFORMED,cmd=URL...,when=1266940789401,modifiers=]
on menuitem0
runPlugin: ij.plugin.URLOpener
setKeyUp: -1

I don't know what setKeyUp: -1 is, but I don't think it has anything to do
with the fact that IJ can't use network.

Browsing debian bugreports, I've found this:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560142#5

Reading through that, following:

http://pvaneynd.livejournal.com/132635.html

and doing the suggested:

echo 0 > /proc/sys/net/ipv6/bindv6only

fixes my problems. But as we know, /proc is not even a real directory, this
is only a temporary solution. The permanent solution would be editing
/etc/sysctl.d/bindv6only.conf and change it there. As I've read from the
debian bugreports, this comes form the "netbase" package.
