Description of problem:

anaconda fails to resolve dependencies when selecting KDE Plasma Workspaces, see
first screen-shot. 

But if one re-selects KDE Plasma Workspaces again, there will be no dependency errors.

It is even possible to start installing but it will fail during installation with the error dependencies, see second screenshot.

Failing Packages: enblend, libgpod, upower

Version-Release number of selected component (if applicable):
F19a TC1 (19.12)

How reproducible:
always

Steps to Reproduce:

0. reach the welcome screen, leave default
1. enter Software Selection and select KDE Plasma Workspaces, then DONE.
2. after anaconda fails to resolve dependencies, enter Software Selection again.
3. select KDE Plasma Workspaces again, then DONE.
4. anaconda seems to resolve the dependencies this time...
5. select automatic partitioning (or whatever works).
6. Start installing, anaconda will hit the dependency error.
  
Actual results:
one can start installing with known dependency problems

Expected results:
no dependency issues, if there are some, do not let the user start installing.
