[Mediawiki-l] litle problems with SQL

[_tonneti]

hi, i am testing my new wiki but have some problems with some options in 
many sections of the wiki, i have this type os message when i want to try 
the special pages, for example "all pages" "my contributions" and other 
ones, this is the message>

(SQL query hidden)

El error de retorno de MySQL fue"1064: You have an error in your SQL syntax 
near 'INDEX (usertext_timestamp) WHERE page_id=rev_page AND 
rev_user_text='Tonneti' at line 5 (sql7)".

i am using 1.5beta4, can this be a bug...¿?¿

greets ;)
