decimal.InvalidOperation without inferred_tolerance_default

[wzyboy]

I encountered this on a bean file generated by a script. Here's a minimal reproducible example:

plugin "beancount.plugins.auto"
;option "inferred_tolerance_default" "CAD:0.01"

2022-10-20 * ""
  Assets:A  -23.71666666666666666666666667 CAD
  Assets:A  -94.86666666666666666666666668 CAD
  Expenses:B

Doing bean-check raises decimal.InvalidOperation: [<class 'decimal.InvalidOperation'>] exception:

Beancount version: Beancount 2.3.5 (git:b40819f4; 2022-07-28)

The exception is not raised if option "inferred_tolerance_default" "CAD:0.01" is enabled.

I'm not sure but this issue might be related to: #584
