launches yagv when opening FOLDER

[whitis]

Critical bug. file-roller will make the system user interface sieze up and cause you to lose work.

- Ubuntu 18.04
- install firefox and yagv
- In firefox, download and select open with archive manager

- In file roller, click on the folder ChepBedLevel2.0
- It will not browse the folder
- Double click on the folder.
- Instead of browsing the folder, It will launch yagv on the g-code files. It might also launch the text editor (gedit?) on the STL file.
- the system doesn't hang every time but it does occur multiple times.
- ssh in remotely and killall file-roller to get control of your machine back.

file-roller is very unresponsive, even with the machine working ok.

Same thing happens with a 3D model with no g-code downloaded from thingiverse containing no g-code.

In this case, it tries to open the huge STL file with a text editor. In this case, I noticed that trying to type in a terminal window caused the text editor search box to appear.

The hangs might be occuring in gedit and/or yagv (never seen that before) but gedit was launched without consent.

This seems to be exciting an existing bug in the system. It not uncommon for certain programs dialog boxes to sieze control of the the mouse pointer and make the machine unusable. I had more trouble than usual recovering, however. Ctrl-Alt-Del and cancel did not work and switching consoles didn't work. I have disabled a few dialog boxes that cause this problem, like the an application is unresponsive, do you want me to make the entire system unresponsive? dialog box.

dpkg -l yagv; dpkg -l file-roller; dpkg -l gedit; lsb_release -a
