If you delete the user , while he is browsing the page.
Then its dies.

"Share Album" plugin creates a user, and if you revoke (Cancel sharing) the access while the user is browsing.
functions_user_inc.php dies at row 348.

I added these rows to avoid the problem:
$user_infos_row = pwg_db_fetch_assoc($result); if (is_null($user_infos_row)) { unset($_SESSION["pwg_uid"]); redirect(get_absolute_root_url()); }

The error message:
