Uninitialized variable "path" in XGFontManager

[Kim Shrier]

I finally tracked down a problem I was having with running applications.

If I had not created a Library directory under the GNUstep directory in
my home directory, ie. ~/GNUstep/Library does not exist, then GNUstep
apps would segfault on startup.

I have tracked it down to the use of the path variable in
XGFontManager.m on line 90.  If the paths array has 0 entries, then
then path is not assigned a value.  This variable is then passed to
the NSFileManager which tries to get the cString value of the
uninitialized path variable, causing the seg fault.

I have included a patch which fixes the problem.  I made a guess
as to what the log message should be.
