Bug Description

To reproduce:
0. Install xsel
1. Open gnome-terminal
2. Run 'seq 150000 | fmt' to produce a lot of scrollback
3. Tripple-click on the last line of output
4. press Shift-Home to scroll to top
5. Shift-click on the first line of output
6. Run 'xsel > /tmp/PLEASEDONTCRASH'

Expected result: no crash

Actual result: all gnome-terminal windows disappear, and this appears in ~/.xsession-errors:

(gnome-terminal:29462): Gdk-WARNING **: The program 'gnome-terminal' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 17484 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.)

Sometimes it doesn't crash at once and I have to repeat steps 3 through 6 a few times.

This appears to be a bug in xsel (with a fix pending at https://github.com/kfish/xsel/pull/1), _and_ a bug in Gtk+ ("Should GTK+ protect itself against selection windows disappearing? Most likely, yes.").
