Hi there

when I perform a search read over all the records, I get different results when performing a search read over one record.

Eg when I do a search read over the field 'cumulated_balance' of the model 'account.move.line',

for all the records: 

...

{'id': 21429, 'cumulated_balance': 145.71}, {'id': 21430, 'cumulated_balance': 47.9}, {'id': 21431, 'cumulated_balance': 29.8}, {'id': 21432, 'cumulated_balance': 18.46}, {'id': 21433, 'cumulated_balance': 1.6}, {'id': 21127, 'cumulated_balance': 0.0}, {'id': 21128, 'cumulated_balance': 1.6}...

when I do a search read only for record 21429 (with filter [[['id','=',21429]]]) I get this result:

{'id': 21429,  'cumulated_balance': 97.81}

97.81 is not the same as 145.71

Is this a bug or have I done something wrong?
