[kmymoney] [Bug 398410] KMyMoney crashes when trying to save entries back to DB Backend

--- Comment #2 from Thomas Baumgart <tbaumgart at kde.org> ---
Part of the 'core dump' is a backtrace. It shows the following, but I have no
idea what is going on. Why would KMyMoney call 'slotFileSave' on a DB backend?
That does not make sense to me at all.
