Summary: kernel32.GetLocaleInfoA/W needs to be more strict
                    about invalid LCTYPE values (Dirt3 installer shows
                    language selection with empty strings)
           Product: Wine
           Version: 1.3.21
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal

Hello,

encountered this while looking at "Dirt 3" game installer ...
The installer enumerates install languages and builds a listbox filled with
empty language strings.

For whatever reason the installer calls kernel32.GetLocaleInfoA/W with LCTYPE
0x73 which seems to be invalid (didn't find any info in MSDN/PDK)?
Wine doesn't validate these "holes" and returns success:

--- snip ---
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x73,0x32ea04,256)
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x73,0x32ea04,256) returning 1
L""

http://source.winehq.org/git/wine.git/blob/HEAD:/include/winnls.h#l296

--- snip include/winnls.h ---
 296 #define LOCALE_IREADINGLAYOUT       0x0070

 298 #define LOCALE_INEGATIVEPERCENT     0x0074
--- snip include/winnls.h ---

If these holes are rejected (ERROR_INVALID_FLAGS), the installer gets it right
and uses a proper way of retrieving language names:

--- snip ---
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x4,0x32ea04,256)
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x4,0x32ea04,256) returning 8

L"United States"
0009:trace:listbox:ListBoxWndProc_common [0x10068]: msg LB_ADDSTRING wp
