small patch for g_dir_open()

[Michael Natterer <mitch gimp org>]

Hi all,

while porting GIMP to g_dir_open() to get rid of our own wrappers
i noticed some __EMX__ portability code which is missing in gdir.c:

   dir->dir = opendir (path);


The g_return_val_if_fail() is absolutely neccessary because opendir(NULL)
simply crashes. The #ifdef __EMX__'s correctness is out of my scope :)
but looks like the right thing to do...

OK to commit?

ciao,
