This bug is related due to missing SQL-Query-Result fields in the function "getMenu()" (in class.t3lib_page.php) called by function "isSubMenu" from "class.tslib_menu.php".
The function getMenu provides a function-variable (operator? - I'm no developer) in which the whished fields for the result rows can be given. Nice feature, but the problem is that the function also does the submenu check (ISSUB etc.) and therefore needs certain fields in the result row. If these are not part of the values passed in the function call, those checks will always fail (which currently does).

Therefore there are 2 possible solutions:
Either parse the field-values passed to the function variable with a t3lib_div::uniqueInList($passed_fields.",".$required_fields_by_function_itself) or simply add those fields to the functioncall in line 1343 of class "class.tslib_menu.php".
The missing fields in the function call are "shortuct" and "shortcut_mode".
