[Mediawiki-l] getThumbUrlFromCache could not write to thumb path

[Enrique]

hi
i'm trying configure $wgForeignFileRepos to see images of wikipedia on
my local wiki. to do have configured to curl request:
$wgHTTPTimeout = 3000; 
$wgHTTPProxy = "http://myProxyIp:Port";
and 
$wgForeignFileRepos[] = array(

'class' => 'ForeignAPIRepo',

'name'                    => 'shared',
 'apibase'                 => 'http://commons.wikimedia.org/w/api.php',
 'fetchDescription'        => false, 
 'descriptionCacheExpiry'  => 43200, 
 'apiThumbCacheExpiry'     => 43200, 

);;

now in my debug.log  see many lines saying
ForeignAPIRepo::getThumbUrlFromCache could not write to thumb path, in
access.log of my proxy i see my mediawiki downloading the images in
images/tumb have many folders as image name but are empty.
