after a fresh install of 13.2 I integrated my old korganizer.ics into the new pim. Then I configured the categories and defined the category colors. After stopping kontact (and korganizer) a short look to .kde4/share/config/korganzierrc seemed ok, color-definitions as expected. After a restart of kontact korganizer displayed hardly any category colors: most were gone. A view to korganizerrc showed a few color-definitions as "invalid" - but much more weren't displayed.
This also happens when I take the fresh std.ics, define a few categories and dates.
It's not really problematic but it's not nice.

Any suggestions?
