Can't load kate tabbar extension (bug report 1664)

I wanted to help test the patch provided in bug report 1664. I am unable to get the tabbar extension to appear in kate. This is true for systems with or without the 1664 patch. I select the check box in Settings -> Plugins but the bar never appears. When I again open Settings the check box is unchecked. Here is what I see in my xsession-errors log: tdecore (KLibLoader): WARNING: KLibrary: symbol not found tdecore (KLibLoader): WARNING: The library libkatetabbarextensionplugin does not offer an init_libkatetabbarextensionplugin function. I see similar stderr messages with the Kate File Templates plugin: tdecore (KLibLoader): WARNING: KLibrary: symbol not found tdecore (KLibLoader): WARNING: The library katefiletemplates does not offer an init_katefiletemplates function. This is a recent git package set from a day ago. Would somebody else affirm this behavior? Darrell
