In php debug mode, errors appear in textareas

Hi camu,

In the settings pages there is a configuration option to specify the number of rows in a textarea, but when that is not specified by the option an errors appears in that textarea.

potential fix follows to show the change, I used array_key_exists and assumed a rows number of 4 but you may have a different opinion on the right fix : )
