When opening unknown file, uses command /usr/scripts/updates (file path)...

[bugzeeolboy]

...instead of using xdg-open or whatever it uses to pick an application for an unknown file. This happens also when opening a directory from another application (eg, opening my downloads folder from firefox)

It will open a terminal with the Linux Lite updates script. Looking in the task manager, it just creates the command "updates /home/bugzee/foo/bar/filename"
I tried sudo rm /usr/scripts/updates, now it opens a terminal with nothing in it.
I tried making /usr/scripts/updates into

Code:

#!/bin/bash
xdg-open $1

and now it won't even open the terminal, it just changes the cursor to 'waiting' icon for a few seconds and stops.
How do I get my normal unknown file handling back?
This happened after an apt-get upgrade a few months ago. I'm using LL 2.0 Beryl.

The correct Menu command for Install Updates is: x-terminal-emulator --geometry=95x25 -t "Linux Lite Updates" -e /usr/scripts/updates
