I use Budgie DM on Ubuntu 19.10 (firstly noticed on 19.04).
I've installed kmplayer using
sudo apt install kmplayer
When I run kmplayer from terminal: $ kmplayer, it runs successfully throwing only:
Invalid Context= "Mimetypes" line for icon theme: "/usr/share/icons/Faba/symbolic/mimetypes/"
Icon theme "elementary" not found.
I can drag and drop videos into it and it plays them.
But when I try to open kmplayer using desktop menu, its icon appears on dock panel and disappears after 15 seconds without main window opening.
Also, when I try to open a video using Context menu -> Open with -> Kmplayer it behaves the same wrong way.
Gnome MPV, VLC, Parole Media Player open videos without issues.
KMPlayer version: 0.12.0b (c) 2002-2016, Koos Vriezen
Why could it be opened by terminal command and could not be opened by Menu item clicking or by opening video using Open with context menu clicking?
