Installation throws notice

Hallo everyone, when running a new installation of the plugin the following notice is thrown:

-->mod_geogebra
++ XMLDB has detected one CHAR NOT NULL column (urlggb) with '' (empty string) as DEFAULT value. This type of columns must have one meaningful DEFAULT declared or none (NULL). XMLDB have fixed it automatically changing it to none (NULL). The process will continue ok and proper defaults will be created accordingly with each DB requirements. Please fix it in source (XML and/or upgrade script) to avoid this message to be displayed. ++

The process runs through, but it is still not nice and any necessary default value is not set.
