Sigil causes a segmentation fault when inserting files if I am running in a Wayland Gnome Shell (Fedora Linux 25) session. The error does not occur when I switch the desktop to run in a Gnome shell Xorg session.

Sigil is popular ebook creator. I have reported this bug to the Sigil folks -
https://github.com/Sigil-Ebook/Sigil/issues/267. I was told there that this has been identified as a bug in QT (https://bugreports.qt.io/browse/QTBUG-55583) and has been fixed there. 

Also told that "Arch Linux at least, has cherry-picked that patch for our qt5-base 5.7.{0,1} packages". Not sure if that is possible for the current QT version in Fedora 25.

Running Sigil from command line I get:

    (sigil:9740): Gdk-WARNING **: gdkwindow-x11.c:5573 drawable is not a native X11 window
    Segmentation fault (core dumped)


Versions: Sigil version: 0.9.6 from the Fedora repos. Desktop is Fedora 25 running Gnome shell, with a Wayland session. All current updates applied.


To reproduce:

I have found 2 ways to recreate consistently :

    From Sigil File Menu, select Add , then Existing Files
    or
    From Sigil Insert menu, select File. Then in the Insert File dialog hit the "Other Files" button.
