Error message:

2: Target seemed not to be a directory! (Shouldn't happen here!)

From class.t3lib_basicfilefunc.php:

/**
 * Removes all dots, slashes and spaces after a path...
 *
 * @param       string          Input string
 * @return      string          Output string
         /
        function cleanDirectoryName($theDir)    {
                return ereg_replace('[\/\. ]$','',$this->rmDoubleSlash($theDir));
        }

Not sure why a dot is being removed from the end of a directory. But a solution would simply be to remove the "\." from the regexp.

This is still an issue with 4.0.0. I second not removing the dot, it doesn't do any harm and after all it is allowed when creating a folder.

Once you created it, neither deleting nor renaming are possible, though... sop you're stuck unless you have direct access to the machine or work around the issues differently.

Attached a patch and sent it to core list.

Attached updated version. This bug only affects systems with
GLOBALS['TYPO3_CONF_VARS']['BE']['forceCharset'] == 'utf-8' && $GLOBALS['TYPO3_CONF_VARS']['SYS']['UTF8filesystem']

The patch moves deletion of trailing dots to the beginning of cleanFileName (b/c in utf-8 environments this code line would never be executed).

Won't fix.
Nevertheless, with 0010313 fileadmin-module will no longer be able to create such directories.
