This seems to be a serious bug in BrowserModel.py, it created indices
using createIndex( row, column, item ) and later on it uses indices that
are given to it (for example in the item() function) to retrieve the
item from a dict. This can't work, using createIndex() will set the
internalPointer() of that index, but internalId() will return some
"arbitrary" value (i.e. -1.....). So BrowserModel.py needs to be fixed
to be consistent, either always use createIndex(row,col,id(item)) or
always use internalPointer() instead of internalId(). 

However a simple replace in all createIndex() calls still doesn't
completely fix the model, it seems that something tries to call item()
with non-source-model indices. I added a print for the pointer and id to
the item() function adn this is the result:

See that there's some refcnt object in the internalPointer and not an
item? I have no idea why sindex would be not valid, but it seems it
is...

On a side not: There's a model testing class available from a TT guy
here: http://labs.trolltech.com/page/Projects/Itemview/Modeltest 
I'll see if I can port this to PyQt4 later today and suggest it as an
addition to PyQt4.
