gnome-screenshot exits with BadWindow (X Windows Error)

Binary package hint: gnome-utils

gnome-screenshot exits cleanly with a return code of 01. It prints a message before it ends however:

The program 'gnome-screenshot' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 4799 error_code 3 request_code 15 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.)

To reproduce this bug:
1. $ gnome-screenshot --interactive
2. Click the "Grab the current window" radio button option
3. Click the "Take Screenshot" Button.

What should happen:
A window should pop up asking you where you want to save the file.

What happens instead:
gnome-screenshot exits cleanly with a return code of 01. It prints a message before it ends however:

This probably reflects a bug in the program.

running:

$ gnome-screenshot --interactive --sync

fixes the issue.
