strange DBI problem (bind call difference)

[alfie]

I have a real strange DBI problem. I'm using DBIx::Abstract for constructing a search function over a message board, but somehow it gives me a real strange error message:

execute called with 2 bind variables when 0 are needed

Has anyone seen this before? This is the code which I am using:

my @what = split(/\s+/, $what);
shift @what if $what[0] eq '';  # skip leading empty fields
my $first = 1;
foreach (@what) { 
    push (@$where, 'AND') unless $first;
    push (@$where, [
                        { subject => ['LIKE', "\%$_\%"] },
                        'OR',
                        { message => ['LIKE', "\%$_\%"] },
                   ]);
    $first = 0;               
}             

$dbx->select({
    fields => 'reference, subject, name',
    table  => 'boardmessage',
    where  => $where,
});

I can't see any mistake in here, still it gives me the above error message. In the debug I found this thing:

DBIx::Abstract::__literal_query('DBIx::Abstract=HASH(0xb92e080)', 'SEL
+ECT reference, subject, name FROM boardmessage WHERE ((subject LIKE ?
+) OR (message LIKE ?))', '%huhu%', '%huhu%') called at /usr/share/per
+l5/DBIx/Abstract.pm line 769

This leave me even more wondering, for there are two ? in the query and two bind values, so I am really wondering where the thing is bailing out? Did I hit a strange error in the module, or am I having something wrong? Please enlighten me, I'm out of ideas here...
