in master: failing tests / no matching locale

Hi,

A great many tests fail in master for me (in my dev tree). I looked
into one of them and it is:

in desktop/source/deployment/registry/package/dp_package.cxx, line 1494:

                LanguageTag descrTag(iter->second.m_sValue);

/usr/include/c++/5/debug/safe_iterator.h:317:error: attempt to
dereference 
    a past-the-end iterator.

Objects involved in the operation:
iterator "this" @ 0x0x7fff558f9b40 {
type =
N11__gnu_debug14_Safe_iteratorINSt8__detail14_Node_iteratorISt4pairIKN3rtl7OStringE24INetContentTypeParameterELb0ELb1EEENSt7__debug13unordered_mapIS5_S7_NS4_11OStringHashE29OString_equalsIgnoreAsciiCaseSaIS8_EEEEE
(mutable iterator);
  state = past-the-end;
  references sequence with type
  
`NSt7__debug13unordered_mapIN3rtl7OStringE24INetContentTypeParameterNS1_11OStringHashE29OString_equalsIgnoreAsciiCaseSaISt4pairIKS2_S3_EEEE'
  @ 0x0x7fff558f9c90
}


iter is defined, since

as

        auto const iter = params.find("platform");


but there does not seem any protection against a "not found"
situation. This seems to be locale-related. I compile with:

--with-lang=fr de nl en-GB

and I run under:

LANG=fr_LU.utf8
LANGUAGE=
LC_MESSAGES=en_GB.UTF-8
LC_ALL=



This hunk looks suspicious to me:

                 // match best locale:

                 {
                     size_t nPenalty = nPenaltyMax;


Whereas before the call to
  param = params.find("locale");
would overwrite the value previously given to "param", now since there
are two separate variables, in the "else" branch it is the result of
  params.find("platform")
that is used.
