$@ is set and $rv is false but no real error occurred. The issue seems
to happen because when the failing $sth->execute() is called, another
two calls to _dbh_execute()  are issued before the first
$sth->execute() returns.

I couldn't really understand why it happens that way, but those
"nested" calls seemed to be somewhat related to
DBIx::Class::Storage::DBI::Cursor since it was being passed as one of
the parameters.
