bug#72254: 29.4; Cannot yank media when image come from Gnome-shell screenshot

[Sébastien Gendre]

Hello,

I got a bug when I try to yank a screenshot made with Gnome-shell into
an org-mode buffer.

From the reply I get on the Org-mode mailing list, the bug come from
Emacs itself.


What I do:

* From the system menu of Gnome-shell, I choose the action to take a
  screenshot

* I took a screenshot from a selected zone, confirm the screenshot and
  got a notification message telling me "You can past the screenshot
  from the clipboard"

* On an Org-mode document, I place the point where I want to past the
  screenshot and call the Emacs function "yank-media"


What I get:

* In the mini-buffer, I get the error message:
  "Wrong type argument: sequencep, image/png"

* If I go into the "*Messages*" buffer, the full error message is:
  "seq-do: Wrong type argument: sequencep, image/png"

* If I enable debug-on-error, here is the full backtrace:

Debugger entered--Lisp error: (wrong-type-argument sequencep image/png)
  mapc(#f(compiled-function (elt) #<bytecode 0x1ebc9d0d6093f55d>) image/png)
  seq-do(#f(compiled-function (elt) #<bytecode 0x1ebc9d0d6093f55d>) image/png)
  #f(compiled-function #'sequence #<bytecode 
0x19945316743f723a>)(#f(compiled-function (elt) #<bytecode 0x94038afefa059ab>) 
image/png)
  apply(#f(compiled-function #'sequence #<bytecode 0x19945316743f723a>) 
#f(compiled-function (elt) #<bytecode 0x94038afefa059ab>) image/png nil)
  seq-map(#f(compiled-function (elt) #<bytecode 0x94038afefa059ab>) image/png)
  seq-filter(#f(compiled-function (type) #<bytecode 0x17bbb7cb3b4b0c6d>) 
image/png)
  yank-media--find-matching-media("x/special-\\(?:gnome|KDE|mate\\)-files")
  yank-media()
  funcall-interactively(yank-media)
  command-execute(yank-media record)
  execute-extended-command(nil "yank-media" "yank")
  funcall-interactively(execute-extended-command nil "yank-media" "yank")
  command-execute(execute-extended-command)


What I expected:

* The image present in the clipboard is attached to the org-mode heading
  and a link to this attachment is created under the point


Versions:

* Org-mode: 9.7.2

* Emacs: 29.4

* Gnome-shell: 46.3.1


Best regards
