So as the title says: the bug is in UTF8Desc function and a SIGSEGV exception may occur at different situations (got mine while trying to preview a date with a 'г. ' (a cyrillic letter) at the end of a date field). Easiest ways to solve this are two:
1) patch the function code:

function UTF8Desc(S: string; var Desc: string): Integer;
var
    i,b: Integer;
begin
  i := 1;
  Result := 0;
  SetLength(Desc, Length(S));
  while i<=Length(s) do begin
    b := UTF8CharacterStrictLength(@S[i]);
   if b = 0 then Break; // <-- insert this line here and voila
    inc(i,b);
    inc(Result);
    Desc[Result] := Char(b);
  end;
  Setlength(Desc, Result);
end;

2) Initialize global format settings at application start, for example:

...
  FormatSettings.ShortDateFormat:='dd.mm.yyyy';
  FormatSettings.LongDateFormat:='dd.mm.yyyy';
  FormatSettings.ShortTimeFormat:='hh:nn:ss'; 
...
