With c-client-2006k empty $dsn in imap_open function cause 100% crash on latest php. This IS the c-client bug, probably fixed in latest c-client releases - did not try them, can find nothing about this issue in c-client changelog.

Empty arguments crash c-client (as c-client-2006k) with "php-cgi: IMAP toolkit crash: Unable to look up user name" followed by php-cgi crash as well. Reproduce code: --------------- <?php echo 'start '; if ( ($link = imap_open($dsn, $username, $password, $flags)) === false ) { echo 'cannt open'; } echo ' finish'; ?> Expected result: ---------------- "imap_open" function should return FALSE in case of missing or empty any of REQUIRED arg.
