[Koha] yaz client error : [109] Database unavailable -- v2 addinfo 'Default'

[Mathieu Saby]

Hello
I can't use yaz-client on a test VM (Koha master, running on Ubuntu12.04).
I have not used yaz-client for months, so maybe I am doing something 
wrong, or something is missing in my install...
Could somebody give me some piece of advice ?

Koha is installed in dev-mode, on a fresh install (made today).
Marc flavor : unimarc
Zebra is working (rebuildzebra -b -x -reset  + ./bin/koha-zebra-ctl.sh), 
and I can search my records in OPAC and staff interface

yaz-client is connecting, but when I try to use scan or f command I have 
got this error : "[109] Database unavailable -- v2 addinfo 'Default'"

==========================

All files on my Koha directory are owned by "msaby:koha"  (in the 
begining it was "msaby:msaby", but I made a chown because I thought it 
could be the origin of the problem)
user msaby belongs to koha group
uid=1000(msaby) gid=1000(msaby) 
groupes=1000(msaby),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),109(lpadmin),124(sambashare),1002(koha)
