Indeed, you need datas inside the tables. I give you all the processes I did before giving up and coming back to Validator 0.4.13 and SMW 1.7.1. I created a test wiki where I put a duplicate of the same database with Validator 0.5.1 and SMW 1.8.0.1 in order to fix the issue. I forgot to tell one thing, there is no cache on this wiki.
 * 1) I upgraded Validator up to 0.5.0 and SMW 1.8.0 and I already had this issue on the main page.
 * 2) I ran the two scripts on the SMWAdmin special page, nothing better.
 * 3) I came back on SMW1.7.1 with Validator 0.5.0, nothing better.
 * 4) I installed Validator 0.5.1 and SMW 1.8.0, deleted all the SMW tables, and restarted the two scripts, nothing better.
 * 5) I ran the update.php maintenance script to accelerate the process and made again the previous point. Even in the line event process, I can see the same error message several times and quite often.
 * 6) Then, I came back to the previous version (Validator 0.4.13 and SMW 1.7.1), ran once again the scripts (with the update.php maintenance script) and all came back to normal.
