possible one line bug in KItemListHeaderWidget::setColumns()
Review Request #129525 - Created Nov. 21, 2016 and discarded
The current logic checks to see if a key is NOT in a hash, and removes it if it isn't. I don't know exactly what's going on, but it doesn't make sense to me to remove something when it's not there so I suspect this is a bug. I changed the logic to check if the hash does contain the key.
Don't know what to test, but make test passes.
