bug#58606: Emacs next pgtk crashes when pasting to other app

Recently discovered a problem, which reproduces this way:
- Open a new emacs instance.
- Yank anything with M-w or select with mouse.
- Paste yanked text to chromium/icecat.

Both browser and emacs are hanging up for a while and after that Emacs
crashes with:

--8<---------------cut here---------------start------------->8---
Fatal error 11: Segmentation fault
--8<---------------cut here---------------end--------------->8---

I was unable to reproduce this bug.  I am also using sway.  Also thanks
for the tip about emacs-next-pgtk.  I didn't know that was packaged!

So I did just reconfigure, and I am now running a wayland only sway
session.

I did notice that I cannot seem to copy text from inside emacs and paste
into chromium or icecat... Chromium seemed to lock up after I tried to
paste into its url bar.  Icecat did not accept the paste, but continued
working...

Same issue here. Just test Emacs(next-pgtk) with Chromium. 
But not with Icecat nor Firefox (from nonguix).

Also, Chromium seem works fine with other applications, tested (Foot
terminal).

Fortunately for me, I've forgotten about Chromium for some time now.
It probably should report to Emacs mailing list.

I just discovered today, that I can copy text from emacs and paste that
text into firefox.  It seems to no longer be an issue for me.  :)

I built a latest emacs from master:
https://git.sr.ht/~abcdw/rde/commit/b03373920c1cc7d8d4b2d64c96f72eed9bb3651a

And it is affected by this issue, so I made a quick and dirty workaround:
https://git.sr.ht/~abcdw/rde/commit/b6aef2d8b34d1166f33629b4b3a1a0f5751f90f9

Unfortunately, I don't see an easy way to backport this fix to Guix.

Probably, this issues should be reported to bug-gnu-emacs.

I will let one of you do the reporting, since this issue no longer
affects me.  :)

I sometimes run two instances of Emacs.  I discovered today, that Emacs
cannot yank from one and paste to another.  When I try to paste I get this
mysterious warning message in Emacs:

"waiting for reply from selection owner."

Disclaimer: Sharing newbie discovery, inviting risk commentary, no warranty :)

A hack to get around clipboarding hangs (which I won't go into here :)
is (if you are safely by yourself on your laptop) this:

Select what you want to copy-paste as usual
(Ctl-Space and move point to end of region)
but then don't copy it with  Mx w --
instead do shell-op on region like
--8<---------------cut here---------------start------------->8---
Esc |
tee /tmp/foo
--8<---------------cut here---------------end--------------->8---
that should write your region into /tmp/foo

Then switch to your other emacs instance and insert
foo contents at point using

--8<---------------cut here---------------start------------->8---
Ctl-x i
/tmp/foo
--8<---------------cut here---------------end--------------->8---

tee should not have added any newline unless you had it in
your selected region, and Ctl-x i should insert verbatim.
(well, probably modulo different encodings in various buffers. Idk :)

If you want to hop between gui and emacs -nw it should work
fine there too. I've tried that.

If you want to do like append-string, adding to the end of foo, use
...|tee -a /tmp/foo
or use separate files ad lib, of course: whatever|tee /tmp/bar

If you want to be a bit safer, it'd probably be good to make
a restricted temp dir like

--8<---------------cut here---------------start------------->8---
$ mktemp -d /tmp/joshclips.XXXXXX.d
/tmp/joshclips.rinY4L.d
$ ls -ltra /tmp/joshclips.rinY4L.d/
total 8
drwxrwxrwt 16 root root 4096 Oct 26 12:59 ..
drwx------  2 bokr bokr 4096 Oct 26 12:59 .
--8<---------------cut here---------------end--------------->8---
(note the restricted write perm just to user, not group)

and then tee to
/tmp/joshclips.rinY4L.d/foo

Of course, if you want to preserve your cutting room detritus,
you can use other directories than /tmp :)

BTW, you could of course plain write foo with Crl-x w
but then you'd get interaction that using tee and insert avoids.

Also you could use cat > or cat >> in place of tee and tee -a
respectively, but then your selected region would disappear
because redirected cat effectively returns '' as the filtered region,
unlike tee which makes no mod, just sneaks a copy.

Using cat you'd have to undo with Crl-underscore.
No big deal, but tee avoids it :)

Please excuse that this wasn't on the fseg topic. SFTN.
