That one's already fixed in SVN:

http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/SemanticMediaWiki/includes/SMW_DataValue.php?r1=67090&r2=67279

I'd say it's an argument for releasing a new version of SMW already, even so soon after the last one...

One of my pages throws a long list of warnings like these :

Notice: Uninitialized string offset: -1 in C:\Data\htdocs\smw\extensions\SemanticMediaWiki\includes\SMW_DataValue.php on line 684

Starting at line 680:

public function isNumeric() {
$sig = $this->getSignature();
$valueIndex = $this->getValueIndex();

return $sig { $valueIndex } == 'n' || $sig { $valueIndex } == 'f';
}

For some reason, it looks like $valueIndex returns -1. Not sure why yet but I will check that out,
