Comment 1 for bug 381910

I have different behaviour in 5.0.6 (also wrong).

I created 2 Products with cost 100EUR, first assigned to linear method asset (5 intervals -> 20%), second to progressive (30%).
And run "Compute Assets".

For linear method I got depreciation 20EUR but Residual 60 (should be 100-20=80).
For progressive method I got depreciation 30 but residual 40 (should be 100-30=70)

It looks that depreciation is counted twice for residual.
And for progressive account sides are wrong. Depreciation should Debit and Fixed assets should be Credit (is opposite). In linear is correct.

And finally I am not able to run "Compute Assets" any more. I tested few times creating fresh database. Every second time I got:
