Testing why the bottom panel doesn't react to mouse clicks
Trying to fix the non-working click with Gtk 3.12
Unfixing the fix, because it didn't fix the bug.
First test to allow NULL in fullPath, to allow to add configuration elements that don't refer to a physical file or path
Fixed a bug that tried to add NULL to the list of folders to exclude
Merge branch 'allow_null_fullpath' into devel
