Arch Linux

Description:

When running a wayland gnome session, I can start calibre but opening a file dialog caused a segmentation fault. I ran calibre under gdb to get the backtrace. From the traces, my guess is that the native dialog is a wayland dialog but calibre is running under xwayland. A quick search for "QDialogPrivate::setNativeDialogVisible(bool)" dit not yield useful results.

I initially opened a bug upstream: https://bugs.launchpad.net/calibre/+bug/1600621
But it was closed because I am using a distribution package. When I tried the "installer" version from 2.62.0, I could not reproduce the crash. So it seems indded that it is not an issue with calibre but something from a dependency.


Additional info:
Package version 2.62.0-1


Steps to reproduce:
Run calibre in a gnome wayland session and click on "add books".

Backtrace:
(python2:7241): Gdk-WARNING **: gdkwindow-x11.c:5555 drawable is not a native X11 window
