gnome_proxy_netmask_ipv6_conversion.patch

Thanks for the nice diagnosis, Carsten.

I'm not familiar with details of ipv6 masks, but, looking at proxy_MaskIPv6Addr, it looks like ipv6 masks of <= 32 are meaningful, and so the conversion should be performed only for ipv4 addresses, as in nsProtocolProxyService.
http://hg.mozilla.org/mozilla-central/annotate/64b497e6f593/netwerk/base/src/nsProtocolProxyService.cpp#l1362

Perhaps add an optional int32_t* aMask parameter to ConvertToIPV6Addr()?
