[web2py] float argument required, not str

[Ciro Alves]

Salve Pessoal

Estou com um erro que não consigo resolver. Eu faço um select onde só estão 
envolvidas variáveis inteiras mas, mesmo assim, recebo o erro acima dizendo 
que uma variável float era requerida.

Segue abaixo a descrição do erro. Não consigo passar do select. E o 
estranho é que sempre funcionou.

Alguma poderia sugerir onde está o problema?
