Update: This post now have a step-by-step instruction on how to install the latest Digikam version on Ubuntu 9.10
It seems like 1.1.0 takes care of several bugs that caused the previous version to crash. You may download a .deb package if you are in a hurry. I tried to install it, but unfortunately the package breaks the "Showphoto". Whatever that means. I guess that the Ubuntu (or Kubuntu) package is too different to allow the OS to just upgrade right away. I'll look into this as soon as I have the chance. But I will also look forward to see Ubuntu 10.04, and hope that the new Digikam version is included in the repositories.
