If the old code had used `m_collator(other.m_collator)` in the copy constructor, construction would have been just a ref count increment and each of the following `m_collator.setFoo(...)` would have been noops (QCollator checks if the new value is different to its current value).

  Is there even a need to have n QCollator objects?
  I'm talking about a QCollator _within_ a given view. Each view could obviously have it's own collator due to different view settings.
