When typedefing a known type and then registering it in the meta type system then it not always return the right id

When typedefing a known type and then registering it in the meta type system then it not always return the right id, sometimes it will return the newly registered one and sometimes it will return the existing one.

Update:
Fixing this problem involves introducing a way for QMetaType to know about typedefs. A qRegisterMetaTypedef() function is one possibility, and we are investigating others.
