Crash when navigating the main menu (Kubuntu)

Issue type

Crash or freeze

Description with steps to reproduce

1. Download the latest Nigthly AppImage (the same happens with stable version 4.5.2).
2. Open it (this happens both when double clicking the appimage, or when running it from terminal. In fact, I'm going to upload what is shown on the terminal in the section down below).
3. Open the menu "Diagnostic". Move the mouse down over "Extensions".
   Note: the same happens when moving the mouse over the "Plugins" entry of the main menu.
4. The application suddenly crashes.
