[PyKDE] QListView returns base instead of sub class pointer

[Torsten Marek]

Hello Phil, hello all

I recently installed sip4 on my machine and so far, it works very fine. 
I even ported my own project from sip3 to sip4. But with another program 
of mine, I am experiencing a strange behaviour:
In a subclassed QListView, there are several hundred items, all of one 
subclasses of QListViewItem. The items get inserted on startup and saved 
on close.
Now, if I traverse the tree (whether by hand or using a generator 
function), the problem occurs that sometimes firstChild() from the items 
returns not a pointer to the python item but to the QListViewItem 
underneath and attribute errors occur. I tried out to isolate the code 
and sometimes no errors occurs, otherwise between one and five wrong 
references.
As mentioned above, I cannot find the source of the problem, so I cannot 
post any code until now, but the program is available from 
http://linux.ratsstar.de/arborfelix/. I think that the problem only 
occurs in sufficiently large trees, so I could post some sample data to 
the list.

So far, maybe I find something which could give a hint

greets

Torsten
