Little cms color engine

LCMS returns some kind of garbage in place of productName when reading this
ICC profile - http://netprint.ru/images/846.zip, this causes segfault in
UFRaw.
The profile itself is probably borked, but nevertheless it would be good
not to crash in such cases.
The problem seems to be somewhere around src/cmsio1.c:1650 - wcstombs()
somehow returns something that is not a valid Unicode, but doesn't report
any errors in the same time.

Valgrind also reports several uninitialized reads, which can be fixed with
simple memset(wchar, .., ..).
Btw, wchar allocation also looks weird to me:
wchar = (wchar_t*) _cmsMalloc(Len*sizeof(wchar_t) + 2);
shouldn't it be
wchar = (wchar_t*) _cmsMalloc((Len+1)*sizeof(wchar_t));
instead?

Let me know if you need any additional info, I'd be glad to provide any
help needed.
