Dear Maintainer,

I used "latexmk -pdf" to create a simple PDF file from the following code:

*****
\documentclass{article}
\usepackage{lipsum}

\begin{document}
\lipsum[1]
\end{document}
*****

Then I used atril to add an annotation, saved the file and quit atril. Opening
the file again and selecting "File --> Open a Copy" from the menu caused a
segfault. Here's the output from running this in gdb:

It would be nice if you could fix this! If you require any further information,
just say so.

With best regards

Dear Maintainer,
I could reproduce this issue by these steps:


- installed a minimal test VM with `apt install systemd-coredump mc xdm xserver-xorg jwm xterm atril latexmk texlive-latex-extra gdb libatrilview3-dbgsym libgtk-3-0-dbgsym libglib2.0-0-dbgsym atril-dbgsym`
- created the PDF by `latexmk -pdf test.latex`
- open atril
- open PDF
- switch the sidebar from "Thumbnail" to "Annotations"
- create a annotation
- save the PDF
- closed atril
- opened atril
- opened the saved PDF
- then "Open a Copy" crashed it


This crashed here:

https://sources.debian.org/src/atril/1.26.0-2/libview/ev-view.c/#L2694

2691 	child = ev_view_get_window_child (view, window);
2692 	gdk_window_get_origin (gtk_widget_get_window (GTK_WIDGET (view)),
2693 			       &root_x, &root_y);
2694 	if (root_x != child->parent_x || root_y != child->parent_y) {
2695 		gint dest_x, dest_y;

         child = 0x0

...
(rr) print view->window_children
$2 = 0x0


The variable child still contains a null here, looks like because
view->window_children is also a null.

Unfortunately found no matching upstream entry in [1].

Kind regards,
Bernhard
