No output on mysqli unavailability.

[eluser]Блум[/eluser]
When mysqli not available and

Code:

$db['default']['dbdriver'] = "mysqli";
$db['default']['db_debug'] = TRUE;

there is no output. No errors in the output, error_log also empty.
Tested on two systems running Linux, PHP 5.2.5, MySQL 5.0.30.

Can you please test it and tell me if it is the same for you and if I should fill a bug report.
Thank You.
