Bug 359471

When buying investments periodically the rounding errors on the account, where the investments are payed from, seem to accumulate. So it might appear, that the payment account suddenly has a saldo differing by +/- 0.01 after an investment booking.

When I edit the corresponding investment booking, the error shifts from this booking to the next one in the sequence. 

When I save, the consistency check reports a problem, that has been fixed. After that, the error is back at the previous booking.


Reproducible: Sometimes

Steps to Reproduce:
1. make multiple investment bookings in a sequence, all rounding in the same direction
2. Save, to get the consistency error
3. after a number of bookings you should see a saldo differing by +/- 0.01
