CTRL, ALT, SHIFT or right-click kills some windows

  • 772

For the last few days, certain desktop applications have started dying whenever the Ctrl, Alt or Shift keys are pressed, or the GUI is right-clicked. This happens on keydown/mousedown.

For example, it happens in:

  • Nautilus
  • Update Manager
  • Rhythmbox Music Player
  • Gnome Screenshot
  • Gedit (only seems to crash on right-click and some keystrokes such as Ctrl+S)

It does not happen in all applications. For example, Chrome, Clion (IDE), Skype, gitk are unaffected.

If I launch nautilus from the command line, then press Ctrl:

$ nautilus
Segmentation fault

Running it with gdb shows the following backtrace:

I've noticed that nautilus looks different since this started happening:

Any ideas how I can fix this?

    I believe you have installed a PPA (probably the elementary-os/daily or the ricotz/testing) that installed a library (or libraries) of GNOME that is (are) incompatible with your system.

    You should purge the PPA that installed the newer version of the library (libraries).

    If you do not have installed ppa-purge, run

    sudo apt-get install ppa-purge

    Once installed remove the PPA with

    sudo ppa-purge [ppa:ppa_team/ppa_name]
