> At first I didn't achieve to reproduce the situation, no warning appeared even with error handler activated. Then, after switching from PHP 5.2 to PHP 5.3, the warning appeared, so it's a PHP 5.3 bug only. I think the PMA demo server is running PHP 5.3.

> But when fetching results from the "SHOW GLOBAL VARIABLES" query (line 232), which returns only sysvar names and values, a type is assigned only if the sysvar hasn't one (line #247) and set to PMA_ENGINE_DETAILS_TYPE_PLAINTEXT (0).
> Elsewhere in the method, even in the whole file, I don't see where a type assignation is done. And it has to be done somewhere since a sysvar that emits the warning is set to ON and has a PMA_ENGINE_DETAILS_TYPE_NUMERIC (2) type, which is incorrect and should be PMA_ENGINE_DETAILS_TYPE_BOOLEAN (3).

in StorageEngine.class.php, the comment for getVariables() says that 
this function is overridden when extending this class for a particular 

So the type comes from libraries/engines/innodb.lib.php in getVariables().
