Why ?
Please look at this code:
// File: testrealpath.c
> #include <stdlib.h>
> #include <stdio.h>
> #include <errno.h>
>
> int testrealpath(const char* path) {
> errno = 0;

> if (NULL == t_realpath_buf) {
> printf("Resolved failed: \"%s\"\n",path);fflush(stdout);
> perror("Resolve failed");
> return 1;
> } else {
> printf("Resolved: \"%s\"\n", t_realpath_buf);fflush(stdout);
> free(t_realpath_buf);
> return 0;
> }
> }

int main(int argc, char **argv)

Output:
>
Resolved: "/"
> Resolved: "/proc"
> Resolved: "/proc/self"
> Resolved failed: "/proc/self/non-existent"
> TypeError: node is undefined

So I get a TypeError instead of a "Resolved failed".
Beside that if that folder appears in my dialogs, it means that is
"somehow" returned by the "scandir" call with de->d_type==DT_DIR, where de
is a pointer to a dirent struct (I'm using the dirent.h header file).
