Description of problem:
libgnome fails to build on linux/alpha
The problem is that function parameter is defined as va_list and caller
tries to pass 0 as a parameter. va_list on alpha is not a pointer.

Version-Release number of selected component (if applicable):
libgnome-2.9.1-3

Additional info:
In attached patch I used dummy va_list variable and passed it, because the
called function checks number of passed parameters first.
