Description:
------------
is_dir() does not work when the folder is an absolute path.

For example is_dir('/mnt') won't work (return false).
But it works for relative path.

Example:

$ php -r 'clearstatcache();var_dump(is_dir("/mnt/"));' bool(false)
$ php -r 'clearstatcache();var_dump(is_dir("./Templates"));'
bool(true)
$ test -d "/mnt/" && echo dir || echo not_dir
dir
$ test -d "./Templates" && echo dir || echo not_dir
dir

Also: safe mode is enabled

is_file() does the same thing when the owner of the file is not the owner of the script.
IMO that's how safe_mode works. 
Wez, is this the expected behaviour or am I wrong?

Sounds like expected behaviour in safe_mode.
