Affects: evolution (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
If I create a custom category to apply to a task and then try to filter
my view by category I only get to see the custom category in the drop
down list while I am in calendar view. If I switch to tasks the drop
down list only shows the default evolution categories. None of my custom
categorie are visible.
