Hello. I faced a weird behaviour. When I try to run an executable file with a mouse click, it opens in an application (it's deadbeef, for some strange reason), even if the executable flag is set. There are no associations with the application/x-executable MIME type in system settings. But if I run an executable from a .desktop file or in terminal, it will run successfully. Dolphin considers all the executables as application/octet-stream.
