I'm running Ubuntu 16.04 with Google Chrome 52.0.2743.116 (64-bit) installed.
When I click on a file in the download section (chrome://downloads/), Chrome seems not to use my systems default application to open the file. It always picks other applications.
If I click on "show in folder", Chrome opens Audacious.
Also I set JavaWS from JDK 8 as my default to open *.jnlp files but Chrome always uses JavaWS from JDK 6.
Other applications like Firefox use the right applications.
Is there something Chrome specific that I need to change as well, when I do changes at my default Applications?

I found out that Chrome uses xdg-open to open files.
I tried to open a file with xdg-open in the commandline. Which opened the same applications as Chrome did. So I viewed the output of xdg-open and found out, that xdg-open called gvfs-open, which was not installed on my system.
After installing it with sudo apt-get install gvfs-bin xdg-open (and Chrome) uses the right applications to open my files.
