Amazon S3 Ireland wrong url

I think there is a bug when enabling Amazon S3 as remote storage in Ireland region.

I enabled it, run the cron manually, photos were uploaded successfully, but the url generated when displaying the picture had a small misconfiguration.

The url was: http://.s3-eu-west-1.amazonaws.com/........../media/com_easysocial/avatars/users/12695/d70397ab5e4b02661c1217b92b49d3b7_medium.jpg

That dot just before the beginning of the url made photos broken.

After a lot of search I found the file administrator\components\com_easysocial\includes\storage\adapters\amazon\amazon.php and around line 117 in function getPermalink I changed this

$url 	= 'http://' . $base . '.' . $this->region . '/';

to this

$url 	= 'http://' . $base . $this->region . '/';

and worked fine.

Can you please verify me if this is the right solution and if there was actually an issue?

Also, I have set up the cron to run automatically every 5 minutes and although I'm getting email notification that it is running, it doesn't seem to run as no pictures are uploaded to S3 and no emails are sent.
When I run the cron manually (having enabled secure cron job) it is working.

In server cron job, do I have to enter the cron url with the secure phrase or without it? (having tried with both although and didn't work)
