Re: Bug#575209: general: Error resolving hostname [resent]

[Resent, because reportbug somehow ate my line breaks, sorry!]

Dear all,

I've found something that is most propbably a bug in Linux's resolv 
system, when trying to open a specific page with Epiphany (but any 
other browser will fail as well, please try out yourself).

To reproduce, please visit <http://www.deviantart.com/> and search for 
"SNES". On the first results page a picture called "SNES World HD" 
should appear. Try to click this picture. Your browser will fail to 
resolv the hostname and even ping won't be able to:

  $ ping KeR-.deviantart.com
  ping: unknown host KeR-.deviantart.com

However, nslookup returns the right IP address and this page even 
loads under both Windows XP and Mac OS X:

  $ nslookup KeR-.deviantart.com
  Server: 134.147.57.130
  Address: 134.147.57.130#53

  Non-authoritative answer:
  KeR-.deviantart.com   canonical name = www.deviantart.com.
  Name: www.deviantart.com
  Address: 8.10.77.140

I believe this bug is caused by the dash character in the domain name, 
but I don't have any further knowledge of Linux's resolv system. As 
you are the experts, please point me to where I can help to trace this 
bug.

Cheers,
Fabian
