Minus at numpad keys

Hi!

here is bug with numpad minus key at usual 102 keyboard

Keyboard (SystemWindow) shows it as < SUBTRACT >
Keyboard (SystemGlobal) shows it as no key pressed.

RenderTTY says
00:10:46 * : [validatevalue: error occured in ](validatevalue: error occured in ): ‘TRACT’ is not a valid integer value

while pressing the key.
thanks
