Bug ID: 360151 Summary: Frequent segfault when a PyQt application exits. Product: plasmashell Version: 5.5.5 Platform: Archlinux Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: anntzer....@gmail.com CC: bhus...@gmail.com, plasma-b...@kde.org At the exit of various PyQt5 scripts, python segfaults fairly frequently. This is *not* (solely, at least) a PyQt related issue, as I cannot reproduce it when using an XFCE session, and the PyQt main developer cannot reproduce it on MacOS (https://www.riverbankcomputing.com/pipermail/pyqt/2016-February/037011.html). Reproducible: Always Steps to Reproduce: Run the following Python script (PyQt 5.5.1, python2 or python3): ``` from PyQt5.QtWidgets import * class Main(QMainWindow): def fail(self): QInputDialog.getItem(self, "foo", "bar", ["baz"]) raise Exception app = QApplication([]) main = Main() main.fail() app.exec_() ``` Actual Results: After selecting a value and raising a (normal) exception, the application segfaults (not always, but more than half of the time). Expected Results: The application should exit with status 1 (failed with exception). a gdb backtrace (without any debug informations, sorry): ``` (gdb) bt #0 0x00007ffff505c01b in ??
