Version: 1.3.80 (using Devel)
Installed from: Compiled sources
Steps to reproduce:
1. Open dolphin.
2. Go to /.
3. Click detail view.
4. Select first item.
5. Hold shift key and press down arrow key repeatedly.
One by one all items should be selected.
Previously selected items are unselected and it selects only 2 items at a time.
This has been reported already, and I think I've found the root cause, so I'm confident that we can fix this before 4.4.0.
