AP Reversal problem in 1.2.9

[Alejandro Imass <..hidden..>]

Hi all,

We had some issues with reversal of both purchasing and sales invoices
in 1.2.8. The sales invoices reversal problem was solved with applying
the files from the 1.2 branch. But the the purchasing invoice is still
duplicating items when re-posted. We upgraded to 1.2.9 in the hope that
it was fixed, but we still have problems with the purchasing invoice. We
are not sure if someone else is experiencing this or not?

Many thanks,
Alejandro Imass
