Description: ------------ PHP warnings WRT invalid arguments to foreach() are thrown when I access my mailbox using MailIMAPv2. Reproduce code: --------------- Line 1182 (in function _getDefaultPid) is as follows: foreach ($this->structure[$mid]['pid'] as $p => $id) { Expected result: ---------------- I've added if (is_array($this->structure[$mid]['pid'] { .. } around the aforementioned loop, and the warnings went away. Suggest inclusion in future releases of package. Actual result: -------------- I get numerous occurrences of the following (using my own error-logging method): Warning: Invalid argument supplied for foreach() in /usr/local/lib/php/Mail/IMAPv2.php on line 1182
