So most probably this is not a CUPS bug as the files missing do not belong to CUPS. The bug is probably caused by whatever package which contains the program which removes the files. As the files belong to snakeoil I add a snakeoil task, perhaps the maintainer of snakeoil knows better how these files can disappear.
