Bug#509976: gcalctool fails to switch trigonometric mode

[Brian Paterni]

Package: gcalctool
Version: 5.24.1

When I click either radio buttons, 'gradians' or 'radians' and switch 
the trigonometric mode from the default of 'degrees' nothing changes. My 
result is in degrees regardless of which radio button is ticked.

I'm using Debian GNU/Linux 5.0
