No. This is look like:

9770  open("winntupg", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 5
9770  fstat64(5, {st_mode=S_IFDIR|0555, st_size=1212, ...}) = 0
9770  fcntl64(5, F_SETFD, FD_CLOEXEC)   = 0
9770  fstat64(5, {st_mode=S_IFDIR|0555, st_size=1212, ...}) = 0
9770  close(5)                          = 0
9770  write(2, "find: ", 6)             = 6
9770  write(2, "mp/i386/winntupg", 16)  = 16
9770  write(2, ": No such file or directory", 27) = 27
9770  write(2, "\n", 1)                 = 1

I`m sure fuseiso return valid struct stat. At least it is not differs from 
stat structures returned on other files.

Good directories look like this:

9770  open("dotnetfx", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 5
9770  fstat64(5, {st_mode=S_IFDIR|0555, st_size=1620, ...}) = 0
9770  fcntl64(5, F_SETFD, FD_CLOEXEC)   = 0
9770  fstat64(5, {st_mode=S_IFDIR|0555, st_size=1620, ...}) = 0
9770  fchdir(5)                         = 0
9770  getdents64(5, /* 37 entries */, 4096) = 1168
9770  brk(0x80bf000)                    = 0x80bf000
9770  getdents64(5, /* 0 entries */, 4096) = 0
9770  close(5)                          = 0

Yes, fuse 2.5.3 -- kernel module & library -- no difference.
