bug#56434: 29.0.50; PGTK cannot yank after second frame is deleted

[Protesilaos Stavrou]

Dear maintainers,

I can reproduce the following on emacs -Q:

1. Produce a second frame with either M-x tear-off-window or C-x 5 b BUFFER

2. Mark a region with some text and type M-w

3. Delete the frame either via the system's window manager or C-x 5 0

4. Type C-y

5. Emacs hangs and displays the echo area message "Waiting for reply from
   selection owner..."

Setting debug-on-error to non-nil has no effect.  When Emacs hangs, the
shell prints this:

    (emacs:2090): GLib-GObject-CRITICAL **: 14:53:23.604: g_object_ref: assertion 'G_IS_OBJECT (object)' failed

I am using the GNOME desktop right now.

Can you reproduce it on your end?  Do you want me to test something else?

All the best,
Protesilaos (or simply "Prot")

Should be fixed now, please test.

Your configure options are mostly redundant.  `--with-xinput2' and
`--without-xaw3d' have no effect on PGTK, and `--with-modules' has been
the default for a long time.

These redundant configure flags make reading generated bug reports
confusing.  Please report the problem to the packager.

Thanks.
