In font_cache we have this code:


paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,
                                              NSUserDomainMask, YES);
  if ((paths != nil) && ([paths count] > 0))
    {
      path = [paths objectAtIndex: 0];
    }
  else 
    {
      NSLog(@"  No valid path for cached information exists. You ");
      NSLog(@"  should create ~/GNUstep/Library by hand");
      return nil;
    }

This makes it unlikely that the failure was in font_cache. More likely other 
code in the library tried to access this directory. A stacktrace of the 
exception would have helped.
