Everything works up until chapter 5, where I get a segmentation fault. I'm running Python3 on Linux Mint 18 with PyQt5 5.7 (built from source to get the latest). Does this example work on anyone else's system with version 5.7? The backtrace follows:<br class="gmail_msg">

It's a regression in PyQt v5.6 - shoul dbe fixed in tonight's snapshot.<br class="gmail_msg">
