The problem is an updated version of libgmp not an updated KDE version. A fix 
is already in git (master and 4.6 branch) since Feb 1st to solve this problem. 
The following patch needs to be applied to older versions.

@@ -164,7 +164,7 @@ QString MyMoneyMoney::formatMoney(const QString& currency, 
const int prec, bool
   // be much better than using KGlobal::locale()->formatMoney.
   bool bNegative = false;
   mpz_class left = value / 
static_cast<MyMoneyMoney>(convertDenominator(d)).valueRef().get_den();
-  mpz_class right = (valueRef() - mpq_class(left)) * denom;
+  mpz_class right = mpz_class((valueRef() - mpq_class(left)) * denom);
 
   if (right < 0) {
     right = -right;


p.s. Sorry 'users', this is more a developers question ;)
