Comment 1 for bug 1584470

I cannot reproduce this, on my linux system. Steps I tried:

1) Click Edit metadata
2) Click the insert link button
3) Click the browse for file on your computer button
4) Choose a file
5) Click OK
6) The resulting link in the Book Details panel opens the previously selected file.

Remember that for a file to be opened when you click it, you need to
have a non-broken implementation of xdg-open on your system
