Thread:Extension talk:Semantic Maps/error with abstract methods in SMGeoCoordsValue

Just installed the semantic maps extension for the very first time to have a "play" with it. Doing so I have hit an error:

From Apache's error log:

[Sun Jun 06 14:47:44 2010] [error] [client 127.0.0.1] PHP Fatal error: Class SMGeoCoordsValue contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (SMWDataValue::parseXSDValue, SMWDataValue::getXSDValue) in /var/lib/mediawiki/extensions/SemanticMaps/GeoCoords/SM_GeoCoordsValue.php on line 317, referer: http://localhost/mediawiki/index.php?title=Sand_Box&action=submit

The error occurred after trying to save a newly created wiki page (no matter whether it contains any map markup or not. The page did however display in the preview properly multiple times before hand, also displaying map elements.

Setup:
 * 32 bit Ubuntu Lucid (10.04) with Apache 2.2 (2.2.14-5ubuntu), PHP 5.3 (5.3.2-1ubuntu4.2) and MySQL 5.1 (5.1.41-3ubuntu12.1) from repositories
 * MediaWiki (version 1:1.15.1-1ubuntu2.1) and Semantic MediaWiki (version 1.4.0-1) from Ubuntu repositories
 * version 0.6.1 of MapsAndSemanticMaps bundle

Tried to reproduce the problem on http://mapping.referata.com/w/index.php?title=Sand_Box, but it failed to show
