Hi all,

I did test the same code by porting it back to *PyQt4* and it works without
any issues. So I can assure you that *the bug is with PyQt 5.6*. Can you
please suggest some ways to view the crash report like in which thread the
crash occured?

I set the primary key as User Data in the QAbstractItemModel. When the user
expands the item I pass this primary key to a QThread which connects with
the server and when the results are obtained, I add children for the
corresponding tree item. When the execution hits the line beginInsertRows
the app crashes. Please help me to fix this issue. Thanks.
