Sebastian, here is the result of the two commands:
=
$ grep png document ~/.local -r
/home/ajlewis2/.local/share/mime/packages/Override.xml:mime-type
type=application/x-extension-jpgcommentjpg document/commentglob
pattern=*.jpg//mime-typemime-type
I moved both files to my Desktop. I rebooted and the problem remains.
I also logged in as another user and did not have the problem opening a
.png. So, it is definitely something with my user.
I did look with dpkg -S to try to determine where the files came from.
They were not a part of any
Ok, here is what I did that works.
cd ~/.local/share/
mv mime bu-mime
Try to open an existing .png and it fails
Right-click/properties/ and choose something other than Image Viewer.
It then opens. Repeat and set back to Image Viewer. It works.
The same works for .jpg and .ogg.
Download
Also changing the file's name will allow it to open:
Double-click linuxreality031.ogg. It fails with the message.
Rename it to linuxreality31.ogg - no change in the extension, just a new
name. Double-click and it opens.
