No, this is not a workaround, the line:
{ return PROXY 192.168.64.1:3128; }
is wrong, this must be:
{ return PROXY 192.168.64.1:3128; }
Then the problem reappears unfortunately.

Downgrading libproxy0 to version libproxy0_0.3.1-2 resolves the
problem.
Additional info:
The problem apparently is related to a wpad config. I have a wpad config
here:
$ wget http://wpad/wpad.dat

var proxy_no = DIRECT;
ipaddr = dnsResolve(host);
if (
(shExpMatch(ipaddr, *:*)) ||

)
{ return proxy_no; }
else
{ return proxy_yes; }
}
When setting the firewall to REJECT the wpad, the problem disappears.
It has something to do with the wpad script (the wpad.dat is linked to
proxy.pac)
VLC is segfaulting on an internal Dreambox (which is on a 192.168
network and thus uses proxy_no), as well as on an external host on
the internet (proxy_yes).
That's why Christophe Mutricy was not able to reproduce the problem I
think.
