They shouldn't rely on that at all. The documentation of QHash says that it 
produces an arbitrary but stable[1] order.

As for the QtDBus problem, I am really not aware of any place where I wrote 
code that depended on a specific order. If that happened, it was an 
unintentional mistake.

[1] note that the order is stable. Two hashing tables with the same elements 
must produce the same order.
