[dev] issue with horde\lib\Share.php

[steve]

With kronolith, I got these errors:
  Undefined index: name in C:\devl\horde\lib\Share.php on line 687

I don't know exactly the job of this function, but it seems that the 
following patch is required:
687c687
<         foreach ($attributes as $attr) {
---
 >         foreach ($attributes as $attr['name']=>$attr['value']) {
