Ok, I talked to Phil on the pyqt list and it seems internalId() is not
reliable in Python due to the fact that in Python id() uses a long,
while in C++ createIndex uses a quint32 and internalId in C++ uses a
quint64 (which is probably a bug anyway). So I created a patch which
fixes BrowserModel and unless I'm mistaken also ProjectBrowserModel, by
using internalPointer and the object-overload of createIndex together
with a list of objects instead of a dict.


Communicate!  It can't make things any worse.
