The issue is probably that 0xFFFFFFFF is a long-int in Python 2.4 while
it was an int in Python 2.3.  PIL accepts an int as a color
specification for RGB images.  But a long-int is a different python
type, and so PIL tries to interpret the long-int object as a tuple which
leads to the error message above.  A simple fix would be to replace the
0xFFFFFFFF with -1.  0x00FFFFFF would probably also work.
