Thunar crashes on "Drag and Drop"

Hello:

Running on an up to date Devuan Beowulf:

groucho@devuan:~$ uname -a
Linux devuan 4.19.0-14-amd64 #1 SMP Debian 4.19.171-2 (2021-01-30) x86_64 GNU/Linux
groucho@devuan:~$ 

Xfce 4.12
Thunar 1.8.4

groucho@devuan:~$ thunar -V
Thunar 1.8.4 (Xfce 4.12)
--- snip ---
groucho@devuan:~$ 

I have come across a problem in Thunar which consists of it crashing when I want to "drag and drop" a file from a folder into another folder.
It crashes the instant I move the mouse to "drag" the file I am "holding" by depressing the mouse's right button.

This happens independently of the location/destination of the file.
ie: within folders in the same drive or from/to to another mounted drive.

"Drag and Drop" is not something I do very often so I cannot say when this started to happen, but it may have started after upgrade to 3.1.0.

/var/log/kern.log, /var/log/syslog and dmesg have a line (obviously the same one) for each time this happens:

Mar 13 14:13:38 devuan kernel: [25529.814724] traps: Thunar[3927] trap int3 ip:7f5fcdb41c75 sp:7ffd5aa20300 error:0 in libglib-2.0.so.0.5800.3[7f5fcdb09000+7e000]

And ~/$ .xsession-errors has this:

(Thunar:3927): Gdk-ERROR **: 14:13:38.788: The program 'Thunar' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 8499 error_code 3 request_code 141 (Composite) minor_code 8)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Any ideas as to to fix this?

Thanks in advance,

A.
