cannot download attachment

[tensor]

Suddenly I was unable to download attachments.
The patch below seems to fix this, but I am not sure that this hack should be applied to show.inc.

=== show.inc

   $OUTPUT->set_env('sender', $MESSAGE->sender['string']);
   $OUTPUT->set_env('permaurl', rcmail_url('show', array('_uid' => $MESSAGE->uid, '_mbox' => $mbox_name)));
+  $OUTPUT->set_env('mailbox', $mbox_name);
   
   // check for unset disposition notification
   if ($MESSAGE->headers->mdn_to &&

The root cause is that something does not pass mailbox in "load-attachment" command. When the piece of code below executes, this.env.mailbox is undefined and the generated URL is incorrect.

      case 'load-attachment':
        var qstring = '_mbox='+urlencode(this.env.mailbox)+'&_uid='+this.env.uid+'&_part='+props.part;

The workaround is to copy the address of the attachment link and paste it into the browser address bar. Luckily the link is generated "statically" in PHP.
