Dear Maintainer,

Since I did a fresh install of Debian 10, nautilus is quite frequently
failing to drag and drop files and folders. By failing, I mean there is
no error on the GUI side, but also it is as if I have never done the
drag-and-drop, everything stays in their old place. I could not find a
certain pattern to replicate the issue but it happens a lot. Also,
after a while this happens, nautilus crashes with segfault (not
always).

In case it matters, I have `gdm 3.30.2-3` and using Wayland.


*** Reporter, please consider answering these questions, where
appropriate ***

   * What led up to the situation?
	Drag-and-drop files/folders (no external drives). No appearant
way to replicate, but happens frequently.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
	Could not find a solution yet.
   * What was the outcome of this action?
	On the GUI side, drag-and-dropped files remain at their old
location, no error displays.
	Here is the relevant part from my syslog:

Same issue with a Debian 10.2 (GNOME) fresh install. Is there any
workaround or news ?

Dear Maintainers,

I experience the same symptoms on a fresh install (Gnome 3 + Wayland),
that is: ~20-30s delayed drag & drop when moving files from within
nautilus, producing various error message popups (attached screenshot
for the most relevant one, others are usually triggered when attemting
to move the same file several times).

It doesn't happen when using keyboard or right-click menu to move the
files.

It happens quite frequently (my first try after a reboot triggered it).

Here are syslog extracts :

Similar reports elsewhere:

- https://bugzilla.redhat.com/show_bug.cgi?id=1808900
- https://gitlab.gnome.org/GNOME/gtk/-/issues/211

According to this last link, there is supposedly a fix:
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/1057
I haven't tested it.

Thanks a lot for any progress on this.

Forgot it.

Dear Maintainer,
