numpad doesn't recognize the comma ',' operator when in english keyboard

[Reinach]

Binary package hint: gcalctool

Since upgrading to Maverick Meerkar 10.10, and when i use the gcalctool calculator, i cannot type the comma ',' operator from the numpad. I ,instead, have to type it from the main keyboard. This occurs when i have English as keyboard language. When i switch to Greek, the comma can be duly typed from the numpad.

Same problem, but when using the German keyboard layout.
Cannot use the comma ',' from numpad in Maverick any more.

I second that - Ubuntu 10.10 with English language but German keyboard layout here. This is a bit annoying, as I use the calculator quite often...
