Could not open dir (/var/lib/amavis/tmp

Hi

I'm using Sophie 3.04rc2 with Sophos, Postfix and amavisd-new. On my last 
install I cannot use Sophie any more. I can start Sophie without any problem.
 
I configured amavisd-new in amavisd.conf :
...
@av_scanners = (

### http://www.vanja.com/tools/sophie/
['Sophie',
 \&ask_daemon, ["{}/\n", '/var/run/sophie'],
 qr/(?x)^ 0+ ( : | [\000\r\n]* $)/,  qr/(?x)^ 1 ( : | [\000\r\n]* $)/,
 qr/(?x)^ [-+]? \d+ : (.*?) [\000\r\n]* $/ ],
);

@av_scanners_backup = (
### http://www.sophos.com/
['Sophos Anti Virus (sweep)', 'sweep',
  '-nb -f -all -rec -ss -sc -archive -cab -tnef --no-reset-atime {}',
  [0,2], qr/Virus .*? found/,
  qr/^>>> Virus(?:(?: fragment)? '?(.+?)'? found)/,
],
);

When I restart amavis, and receive my first messages, I get this error 
message :
