thumbnailers: bwrap can change mime type
The sandbox binds the file to thumbnail as /tmp/gnome-desktop-file-to-thumbnail
, as such name based mime-types can break
This can have interesting results as a file matches a thumbnailers MimeType=
, but when the thumbnailer actually gets the file it sees text/plain
and doesn't know what to do with it
Since the thumbnailer is already reading the file exposing it as /tmp/gnome-desktop-to-thumbnail/$FILENAME
seems harmless enough
