phppgadmin -- "formLanguage" local file inclusion vulnerability

A Secunia Advisory reports:

A vulnerability has been reported in phpPgAdmin, which
can be exploited by malicious people to disclose sensitive
information.
Input passed to the “formLanguage” parameter in
“index.php” isn’t properly verified, before it is used to
include files. This can be exploited to include arbitrary
files from local resources.
Successful exploitation requires that “magic_quotes_gpc”
is disabled.
