In the user account that has has the search bar, when you use configure toolbars, does the "search" feature show up in either the left or right window? If it does what is it's name?
The search toolbar is not in the list.
If it does not show, you might have an "orphan" issue where the search feature was discontinued in the upgrade version but the upgrade process left it in when upgrading KDE.
I just tested creating a clean profile. The search toolbar still is not in the list. I'm guessing the searchbar is hard-coded into the Location bar.
I'm guessing the rsync option is hard-coded too.
In my KDE 3.5.10 setup I don't have the search toolbar showing. The searchbar plugin is installed. After all these years I don't remember how I disabled the search bar. I don't have the rsync plugin installed in 3.5.10.
On "clean" installs I have had toolbar features like that disappear on later versions and I have had to edit the appropriate *ini files to put it back in. I have done this mostly with Kate since Konqueror in its default "installed" layout does what I want. With an upgrade the features were retained because KDE continued to use my original *.ini files from my home folder.
I'll have to tinker. I think the toolbar layout is defined in $HOME//.trinity/share/apps/konqueror/konqueror.rc.
I have disabled (unchecked) the options in the Settings/Extensions menu. No effect.
I suspect a brute force method of removing those options is to remove the plugins. I am not passing judgment on these features --- I see their usefulness. My concern is for those people who don't want the features. They should be able to disable them using the normal options. Right now I can't find the option to do that.
This is a usability issue, not a performance or stability issue.
Unless somebody has an answer then this is starting to look like a bug.
