[Kmymoney] Delete/Correct Account Currency Entries

[timothy]

Hi

I have a problem with spurious currencies. I saved my .kmy file to .xml
and identified the entries which are similar to below:-

 <ACCOUNT currency="E000027" description="" parentaccount="A000353"
opened="2008-05-07" number="" lastmodified="2014-08-08" type="15"
id="A000388" lastreconciled="" institution="" name="............">

The currency "E000027" is not valid and throws up errors in the Tools >
Update Stock and Currency Prices option.

How would I go about changing the E0000.. to the base currency in
the .kmy file? There is no way that I can see to delete these entries.
They only show up in the Tools > Update Stock and Currency Prices and
cannot be deleted there.

Any help would be appreciated.
Regards

Timothy
