<body>Dear Scott,<br><br>thanks for your answer.<br><br>I have no idea where I should search. <br><br>I've
added some print commands to get an idea whats leading to the mentioned
fault. It seems that the eventFilter is the main call during a drag
& drop. I'm sorry, but I do pyqt since just a half a year and I am
still python beginner. So it its stupid, please tell me.<br>The following calls lead to the crash during drag & drop inside a QTreeView.

</blockquote></div><br><br></div><div class="gmail_extra">Where are the ZeroMQ (ZMQ) messages going (when successful)? The errors are definitely coming from ZeroMQ.Do you get any messages received on the other end of the message queue when this happens? It sounds like ZMQ isn't fully initialized or ready to send & receive at that point in your code. My small amount of experience with ZMQ found it to be relatively easy to set up and use. I'd suggest checking whatever is on the other end of the line. <br><br></div><div class="gmail_extra">-Scott<br></div></div>
