gtk program failure?

["d.henman" <dhenman gmail com>]

In the gtk suite, the program gtk-update-icon-cache does not seem to honor
it's " --force" flag.   During an aborted make and trying again I receive the below:

----- back trace

GDK_PIXBUF_MODULE_FILE=../gdk-pixbuf/gdk-pixbuf.loaders ./gtk-update-icon-cache --force --ignore-theme-index		\
	   --source builtin_icons stock-icons > gtkbuiltincache.h.tmp &&        \
	mv gtkbuiltincache.h.tmp gtkbuiltincache.h
gtk-update-icon-cache: Failed to open file stock-icons/.icon-theme.cache : File exists
make[2]: *** [gtkbuiltincache.h] Error 1

N.B. This only happens after an "invalid cache" make.  That means to me that "gtk-update-cache" is erroneously parsing its arguments.

Replys?
