Handle crashes of the thumbnailer child process a
little more gracefully.
* theme-thumbnail.c:
(generate_theme_thumbnail): if we get an EOF from
the child close the pipe, return NULL and return
NULL from any subsequent calls.
(generate_theme_thumbnail_async): return NULL if
the pipe has been closed.
(theme_thumbnail_factory_init): set pipe descriptos
to zero after closing them.
