GIMP crashes with CTRL+X in layers window

[thedoctar]

I am editing a gimp .xcf file with multiple layers. When I use the keyboard shortcut CTRL+X which should cut the layer, GIMP crashes. I can reliably reproduce this bug.

Here is what I get when I run gimp --debug-handlers:

    using gegl copy
    gimp: GEGL-WARNING: (../gegl/buffer/gegl-tile-handler-cache.c:1076):gegl_tile_cache_destroy: runtime check failed: (g_queue_is_empty (&cache_queue))
    EEEEeEeek! 1 GeglBuffers leaked

Here is what I get when I run gimp --debug-handlers --stack-trace-mode always --sync

using gegl copy
The 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 43590 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.)
