socket() address family not supported by protocol

[ghettocitizen]

This message appears very often in teh output of very different programs, for example Firefox/Swiftfox, Thunderbird, Mplayer
In case of Mozilla apps it sometimes freezes KDE interface too (can't switch windows or panel does not pop-up) for a few seconds.
IPV6 is not compiled into kernel and module is not built. It is disabled on the eth0 interface too.
Is this a bug?

Heh, old thread, but I ran into this issue today and found the solution. Put these two lines in the ~/.gtkrc-2.0 file:

gtk-enable-event-sounds=0
gtk-enable-input-feedback-sounds=0

Turns out this is an issue with GTK+ apps (like Firefox) that try to connect to port 4713, the PulseAudio port. Since I don't have PulseAudio installed, those socket connections failed. I normally run Firefox from a menu, so I never saw those error messages. Only today when I was running Firefox from the command line did I notice it.

The bigger issue is why on earth are GTK+ apps trying to use sound when clicking on various menus (like the Tools menu in Firefox)? That's ridiculous.
