Unclosable error window bug

[gustavomarinovando]

The bug in question happens whenever you delete a file from the session and jump next to a file that has been deleted outside MLV-App, whether via terminal or using an explorer (not sure if this matters), you'll get an error that file doesn't exist and after closing the window it tries to open the same file and you get the same window.

Only fix I was able to do was moving a valid MLV file with the same name as the missing file into the folder where it should be.
