Regression see http://bugs.winehq.org/show_bug.cgi?id=4250

The set last error function added to GetMenuStringA and GetMenuStringW 
removed this check which seems to be still needed.
if (!IS_STRING_ITEM(item->fType)) return 0;

I have tried several times to make a patch of the changes required but I 
get a lot of white space changes.

Hi Paul,

Here is a better fix (because it does not make any regression test
fail). Let me know if it works for you too.

Changelog:
dlls/user		: menu.c
dlls/user/tests	: menu.c
Prevent a crash in GetMenuStringA caused by calling strlenW on a NULL
pointer, with a test.

Rein.
