Description John Freed 2016-11-27 18:06:36 UTC 
Description of problem:
Using Wayland after upgrade to F25.

Open rosegarden. Use the "File / Open..." menu. Program crashes.
It also crashes upon a "File / Save As ..." after a successful file open from "File / Open Recent /".

When running from the terminal, I get the following when it crashes:

(rosegarden:6486): Gdk-WARNING **: gdkwindow-x11.c:5554 drawable is not a native X11 window
Segmentation fault (core dumped)

Suggested elsewhere that "The troublemaker here will most likely be xembed and/or the Qt5 gtk QPA." 
and "the problem will be the qt5 gnome qpa hard-assuming wayland"
See https://bbs.archlinux.org/viewtopic.php?id=218680 and https://bbs.archlinux.org/viewtopic.php?id=218831

As suggested elsewhere, thre are two workarounds:
-- start app with GDK_BACKEND=x11 rosegarden
-- use the gnome-x11org login, which essentially applies the above to all apps, IIUC.

The workaround produces this error upon using the "File Open..." dialog
"Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged."

It would appear that this is a known bug (fixed Sept. 21, 2016) in https://github.com/MartinBriza/QGnomePlatform

I can confirm that this is a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1392605

And the proposed solution in "Common Bugs" worked

sudo dnf install qgnomeplatform

It certainly is odd that you set the environment variable QT_QPA_PLATFORM to qgnomeplatform by default but don't install qgnomeplatform by default!
