It seems like it happens for "foo/", too. If I compile:

-- >8 --
#include <glob.h>
#include <stdio.h>

int main(int argc, const char **argv)
{
	while (*++argv) {
		glob_t r;
		if (glob(*argv, 0, NULL, &r))
			perror(*argv);
		else {
			size_t i;
			for (i = 0; i < r.gl_pathc; i++)
				printf("%s -> %s\n", *argv, r.gl_pathv[i]);
			globfree(&r);
		}
	}
	return 0;
}
-- >8 --

I get:

  $ rm -f foo bar
  $ touch foo
  $ ./a.out foo foo/ 'foo\/' bar bar/ 'bar\/'
  foo -> foo
  foo/ -> foo
  foo\/ -> foo
  bar: No such file or directory
  bar/: No such file or directory
  bar\/: No such file or directory
