Seems really to be PHP 5.3 only. Before str_cmp() didn't bleat about the array.

I tracked this down a little.
I have set 'german' and clicked on save:

the following variables want to get compared by strcmp:
$settings[selectedLanguages] = "a:1:{i:0;s:2:"de";}"
$CHANGED_SETTINGS[selectedLanguages] = Array(0 => 'de')

for e.g. two languages, these are the variables:
$settings[selectedLanguages] = "a:1:{i:0;s:2:"de";}"
$CHANGED_SETTINGS[selectedLanguages] = Array(0 => 'de', 1=>'en')

Conclusion:
If $CHANGED_SETTINGS[$key] is an array, THEN the serialized array has to be compared with $settings[$key]:

if (is_array($CHANGED_SETTINGS) && isset($CHANGED_SETTINGS[$key])) {
if ( !is_array($CHANGED_SETTINGS[$key]) && strcmp($settings[$key], $CHANGED_SETTINGS[$key]) ) {
$settings[$key] = $CHANGED_SETTINGS[$key];
$changed = 1;
}
if ( is_array($CHANGED_SETTINGS[$key]) && strcmp($settings[$key], serialize($CHANGED_SETTINGS[$key])) ) {
$settings[$key] = serialize($CHANGED_SETTINGS[$key]);
$changed = 1;
}
}
