Re: SVG to PNG

PS Please register a bug in blob.c
If MagickLibConfigPath is shorter, i.e. has a shorter length, then when
iterating the path_map , first the MagickShareConfigPath is iterated, than
the LibConfigPath:

# if defined(MagickShareConfigPath)

  AddConfigurePath(path_map,&path_index,MagickShareConfigPath,exception);

# endif /* defined(MagickShareConfigPath) */


# if defined(MagickLibConfigPath)

  AddConfigurePath(path_map,&path_index,MagickLibConfigPath,exception);

# endif /* defined(MagickLibConfigPath) */
...while(MagickMapIterateNext(path_map_iterator,&key))
...      FormatString(test_path,"%.1024s%.256s",        (const char
*)MagickMapDereferenceIterator(path_map_iterator,0),        filename);
      file=fopen(test_path,"rb");      if (file )
         if (blob)            break;
...

The above means that path_map iterations would try to open a file with
a test_path contains the LibConfigPath with additionally what's
remaining from the ShareConfigPath...

The fix is to initialize the test_path in the loop (i.e. for each
iteration):char        test_path[MaxTextExtent] = "";
