Bug #1387328 reported by Marius Gedminas on 2014-10-29

apport (Ubuntu)

Bug Description

1. Wait for a crash or run apport-bug /var/crash/something.crash
2. Click Show Details
3. Scroll down the tree view until you see something interesting like Stacktrace
4. Click 'Stacktrace' to expand it

What happens:
- tree view gets focus, 1st (i.e. topmost) item in it gets selected and scrolled into view

What I expect:
- tree view gets focus, the 'Stacktrace' item gets selected and view is not scrolled away from what I was interested in.

Bug in GTK+?

What breaks this is inserting the overlay between the treeview and it's scrolledwindow. Putting the overlay outside makes it work.

I tried to fix this in the code by adding one more level of .getparent() in add_spinner_over_treeview, but simply removing the scrolledwindow and adding it back moves the details to the bottom of the vbox, putting the checkboxes above it. Not nice. So instead of that I moved the Gtk.Overlay() into the .ui file.

(I attempted to also move the spinner to the .ui file but failed miserably: the tree view stopped receiving mouse events as soon as I put a <child type="overlay"> with the spinner. And since moving everything to the .ui made the patch bigger, I gave up and went with the smaller change.)
