Just had this happen for the first time in a while too.
Not sure if this is any help in finding the cause or not but here's some info on it.
I have an unbound file named current.gpx, it's a 2.9 kb GPS eXchange file, part of a Garmin GPS install.
When I right click & Open With Other Application I get the message: "We will now fetch the updates list, Click Yes to continue or No to abort".
Clicking No results in the following System Log entries:
Code:
Nov 13 17:10:19 home-MS-N014 sudo: home : TTY=unknown ; PWD=/home/home/Desktop/Garmin/GPX ; USER=root ; COMMAND=/usr/scripts/updates-gui /home/home/Desktop/Garmin/GPX/current.gpx
Nov 13 17:10:19 home-MS-N014 sudo: pam_unix(sudo:session): session opened for user root by (uid=0)
Nov 13 17:10:22 home-MS-N014 sudo: pam_unix(sudo:session): session closed for user root
Clicking Yes it then updates the Software Sources & checks for updates (via the GUI not Terminal, which I cancelled once checked) with these log entries:
Code:
Nov 13 17:22:33 home-MS-N014 sudo: home : TTY=unknown ; PWD=/home/home/Desktop/Garmin/GPX ; USER=root ; COMMAND=/usr/scripts/updates-gui /home/home/Desktop/Garmin/GPX/current.gpx

From memory I think the way I got around it in the past was to right click & Properties on the file, change what it opens with from No Application Selected to the desired program.
Also from memory but I'm not 100% sure, I think this issue started with the introduction of the GUI for updates.
