[Evolution] Cannot Create New or Delete Existing Categories

[Arthur Machlas <arthur machlas gmail com>]

Greetings,

Using Evolution 2.30.2 on Debian Squeeze I attempt to create a new
category, assign an icon and create, however, the new category is not
created.

Similarly, when I delete the default categories I do not want, e.g,.
VIP, say ok then close. When I next reopen the categories all those I
deleted have been recreated.

I have checked the permissions on my /home/arthur/.evolution folder,
and I am the owner of all files and subdirectories.

Please advise, many thanks!
