[PyQt] PyQt5.6 with Python 3.5 Crash

[Rathinam Signup]

Hi Florian,

Thanks again for the response.

>Wouldn't it be easier to just use a QStandardItemModel with
>QStandardItems

Maybe. But I developed this code based on the simpletreemodel provided with
PyQt Examples>Item Views. So continued with it.

>Does your model call begin* and end* appropriately?

I haven't used InsertChild at all in my code. I always add beginInsertRows
before append child and endInsertRows after it's appended. In this line,
the app is crashing.

>This seems wrong, your leaf items dont have any children.

I intentionally returned True. When the user expands the item I connect
with the server and check for children and if it doesn't have any children,
No children text is added to the tree.

Do you know how can I view the crash report in PyQt? Thanks
