well, you do make sure that the file exists in the right place.

bitmap="@/test.xbm" means something like: look for a bitmap file
named test.xbm at location "/" , that is, at the top level directory.

bitmap="@c:/test.xbm" is equivalent.

some solutions:
1) copy (or cut)  and paste the file test.xbm to c:/ and continue to
use your code or,
2) if test.xbm is in the same directory as your code, you may write:
bitmap="@test.xbm" or bitmap="@./test.xbm"
where "./" means the current directory or,
3) you may write something like (one single string!):
bitmap="@C:/Documents and Settings\Wim/Mijn
documenten\Python/test.xbm"

notice also that if the bitmap appears in your button,
your text="nieuw" may not be visible.
