Libreoffice opens slow, waiting for invalid DNS entry 'hostname.(none)'

[Adam]

When opening a document with Nautilus, Libreoffice starts opening, then takes around 30 seconds on the Logo, waiting for the DNS server to reply to an invalid DNS request. The request looks like this: hostName.(none)

Dumping the TCP request when opening Libreoffice:

root@hostName:/home/bea# tcpdump -nnl -i any -s 1536 dst port 53
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on any, link-type LINUX_SLL (Linux cooked), capture size 1536 bytes
12:06:05.996614 IP 192.168.1.100.55538 > 192.168.1.1.53: 22376+ A? hostName.(none). (41)
12:06:10.998698 IP 192.168.1.100.55538 > 192.168.1.1.53: 22376+ A? hostName.(none). (41)
12:06:15.999297 IP 192.168.1.100.43570 > 192.168.1.1.53: 34259+ A? hostName.(none). (41)
12:06:21.003214 IP 192.168.1.100.43570 > 192.168.1.1.53: 34259+ A? hostName.(none). (41)

WORKAROUND:

adding that invalid DNS name into your /etc/hosts file fixes the problem:

root@hostName:/home/bea# cat /etc/hosts
...
127.0.1.1 hostName.(none)
...

As this bug has been reported and closed multiple times with annoying reasons (for instance: 'there is no openoffice support any more' - LOL, but the source is the same dude!!), please, take a short time and check and fix this now.

Many people are complaining about this on forums and hacking the hosts file themselves. I MUST be fixed in the distribution.

(please, do not bother me with questions, like: ok, have you got enough ram/cpu/disk/screensize... have you known that you can disable logo... is it always like that... the answer to all these questions is: YES).

Thanks!

Ah, one more YES to some weird question: have you done an apt-get update, apt-get upgrade?

Hmm - I'm confirming this because I can partially recreate this here. I'm not seeing a significant
hang, but wireshark is showing me the DNS query issued, but my DNS server is responding with no such name quickly.

For me, the queries are for major.(none) and major.(none).home.treblig.org - where major is the hostname of the machine.

So libreoffice is somehow causing odd DNS lookups, and I can believe some DNS servers might get upset.

Adam,
  Do you have the links to older bugs that were closed and the forum discussions - it would be good to link to them in this bug.
