Error to render compiling AST KeyError: 'digits'

[bitsnaps]

Hi, I got an error when trying to print Manufacturing Order Report in MRP module at smile_decimal_precision/report/ir_qweb.py, it says Error to render compiling AST KeyError: 'digits', looks like there is no digits key in self.env, wouldn't be better to check if digits key available first?
