Hi all,
Because tweetbutton_block_info() returns nothing, it causes a problem in _block_rehash() in block.module (_block_rehash() runs a foreach() against a null value because tweetbutton_block_info() returns nothing). I propose removing that empty hook:

- * Implementation of hook_block_info()
- */
-function tweetbutton_block_info() {
  * Helper function to build the required tweet attributes
  * @param $object
  *   Entity object can either be (node, user, taxonomy)

Thank you. I had this error gone now "Warning: Invalid argument supplied for foreach() in _block_rehash() (line 385 of /mysite/modules/block/block.module)"
