A while ago, my Search Toolbar bar went missing in dolphin.
I'm referring to the Search Toolbar found under Settings>Toolbars Shown>Search Toolbar. I used to sit at the very top right corner of the window.
If the search toolbar is checked for view/unhide, the toolbar looks to activate something, as there is a slight shift in the interface buttons, but the text field is gone from the toolbar.
I tried reconfiguring with dpkg, purging and reinstalling, etc.
I left it alone as I thought it would be fixed in an update, but today I upgraded dolphin and it's still gone. This appears to be a 4.6 bug or something.
