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.

    This sounds like a distro issue. Has any other user of Mageia 3 reported this? Try asking at

    Does this happen with the Qt Creator shipped by Mageia or one that you downloaded from

    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;-).

    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.
