Appaulingly slow DNS resolution from gnome apps

[Chris Smith]

Hi,

I'm getting a nasty problem with Gnome 2.6 on 4.10-RELEASE.  Any apps
with a GTK2 UI (evolution, firefox) are having real issues doing DNS
lookups.  They time out regularly.  Nslookup on the same hosts is
instant.

Anyone seen this or know how to fix it?

Thanks all,

- Chris.
