Comment:

 I tried this again in 13.1.0 os30 and the error in {{{shell.log}}}
 disappeared (without applying my patch).

 I researched this a bit more and I found that the problem seems to be in
 Paint Activity instead of the Clipboard because Paint fails when I try to
 open the clipboard object from the clipboard menu: with "Open" (there is
 no Activities to select, it opens only with Paint).

 On the other hand, if I click on "Keep" from the clipboard menu and then
 open it with ImageViewer I can see the image properly but if after I click
 on "Keep" I open it with Paint I see a white canvas.

 In both situations (open it with Paint) I'm getting this error in Paint
 log:
 {{{

 }}}

 I see two things here:
  1. the path does not exist immediately after Paint is opened
  1. Paint is trying to open a 'png' and the image is 'bmp'
