[TYPO3-ttnews] DBAL fatal error

[mario]

Hi

do you know what it means:

DBAL fatal error: No handler found in handler_getFromTableList() for:
"tt_news_cat INNER JOIN tt_news_cat_mm ON (tt_news_cat.uid =
tt_news_cat_mm.uid_foreign) INNER JOIN tt_news ON (tt_news.uid =
tt_news_cat_mm.uid_local)" (SQL engine parse ERROR: No join fields found
in parseFromTables()!: near "(tt_news_cat.uid =
tt_news_cat_mm.uid_foreign) ")

any idea?
A friend of mine was trying T3, and run into this kind of error. 
He installed  t3 4.1.6


thanks mario
