Qt Creator segfaults when screensaver comes up



  • I have Qt Creator 2.7.0 Based on Qt 5.0.2 (64 bit) that came with Linux distro called Mageia 3 that crashes every time the screen saver comes up.

    I ran Qt Creator from the konsole and now I see it makes a segmentation fault.

    This annoying because every time I relaunch it says files were loaded from backup or something and sometimes they are not complete.

    I made it save a backup copy every one minute for more complete backups.

    The strange part is that it only crashes when the screen saver comes up or when it terminates. I have launched so many other programs and nothing makes Qt Creator crash. Even when I lock the desktop and unlock it Qt Creator doesn't crash. It crashes only when the screen saver comes up on it's own.

    I don't have any seti@home or bitcoin mining screensavers. All I have is the usual Linux OpenGL screensavers. Currently I am using the plain Clock screen saver.

    Hi,

    This sounds like a distro issue. Has any other user of Mageia 3 reported this? Try asking at http://www.mageia.org/en/community/

    Does this happen with the Qt Creator shipped by Mageia or one that you downloaded from qt-project.org?

    Note that 2.7 is rather old, as is Qt 5.0.2. Especially Qt 5 got a lot more stable since then. I would highly recommend to build Qt Creator 2.7 against Qt 4 (or Qt 5.2, but we never tested that since Qt 5.2 was not out when we were working on Qt Creator 2.7;-).



  • I have reported it at bugs.mageia.org
    https://bugs.mageia.org/show_bug.cgi?id=12318

    This problem is manifested with Qt Creator that came from Mageia 3.

    Man, Qt is progressing too fast in too many dimensions at once. I can't keep up.
