Bug#952440: gimp: crashes on Edit then Copy

[Philip]

Package: gimp
Version: 2.10.8-2
Severity: important

Dear Maintainer,

If I open this image in Gimp

http://pscan.uk/images/myx350/DSC_4791.JPG

then I use the rectangle select tool to select a box
then I click Edit then Copy then Gimp immediately dies.

When I run from strace this is the last few lines:-

recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\3\336y\6\0\300\1\0\0\22\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32
writev(3, [{iov_base="+\0\1\0", iov_len=4}, {iov_base=NULL, iov_len=0}, {iov_base="", iov_len=0}], 3) = 4
poll([{fd=3, events=POLLIN}], 1, -1)    = 1 ([{fd=3, revents=POLLIN}])
recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\1\2\337y\0\0\0\0\342\1\300\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32
openat(AT_FDCWD, "/usr/share/X11/XErrorDB", O_RDONLY) = 16
fstat(16, {st_mode=S_IFREG|0644, st_size=42077, ...}) = 0
read(16, "!\n! Copyright 1993, 1995, 1998  "..., 42077) = 42077
close(16)                               = 0
write(2, "The program 'gimp' received an X"..., 562The program 'gimp' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 96734 error_code 3 request_code 18 minor_code 0)
  (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 --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
) = 562
exit_group(1)                           = ?

My system is running LXQT but I don't know if that is relevant...
