Public bug reported: Binary package hint: hplip
This bug is derived from #497877. In that bug, a reviewer of my patch determined that hp-systray (sometimes) segfaults when you quit the tray app. I determined that the bug was also present in hplip without my patch. Essentially, the python c module in pyqt can become... lets charitably call it "confused"... when python destroys objects in an order it isn't expecting. So, when exiting hplip, python's garbage collection runs (or doesn't) and triggers the edge case (or doesn't). There are many discussions of this on the pyqt mailing lists, and each time the suggestion was to do one of the following: 1) instantiate your objects in a different order, until you find an order which doesn't cause the problem 2) figure out which object(s) is causing the issue, and explicitly kill it before you call QApplication.quit() This message on the topic is somewhat enlightening: http://www.mail- archive.com/p...@riverbankcomputing.com/msg20499.html ** Affects: hplip (Ubuntu) Importance: Undecided Status: New -- hp-systray segfault on quit https://bugs.launchpad.net/bugs/546816 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
