kio_groupwise.so should be in kdepimlibs5
Kontact provides the functionality to connect to Novell Groupwise for as long as i know it.
After upgrading from Hardy straight to Jaunty, i couldn't connect to Groupwise anymore and Kontact complained about a missing "kio_groupwise".
I finally found it in the package "kdepim-dev" and manually extracted it from the .deb and moved it into its destined location.
I think - if Kontact allows you to connect to Novell Groupwise resources - the library should also be part of the package that all the other connectors are in. From my point of view it doesn't make sense (and is counter-intuitive) that you have to install "kdepim-dev" just to use a functionality that should work out of the box from the viewpoint of Kontact (apart from the user being forced to install tons of dependency packages just for one file)...
