xcalc displays a comma for divide instead of a forward slash

[Joshua Miller]

xcalc has buttons down the right side. In an older release, those used to be:
AC
DRG
y^x
/
*
-
+
=

Right now, my system is displaying:
AC
DRG
y^x
,
*
-
+
=

Using the "," button works as the divide key. I have no idea why it's displaying a comma instead of "/" or "÷".
