failing to add fonts to the fonts path.

[atar]

Hi there!!

When I trying to add fonts files to the fonts path using the 'xset fp+  
my-font-directory' command, although I have ran the command mkfontdir  
before that, I get the following error message:

xset:  bad font path element (#7), possible causes are:
     Directory does not exist or has wrong permissions
     Directory missing fonts.dir
     Incorrect font server address or syntax

note that the permissions for this directory and all its descendants are  
u=rwx.

What's the problem?

Thanks in advance!!
