Description of problem:
When I first started sylpheed-claws it showed the privacy options in the account
configuration, e.g. whether to always sign a message but there was no default
"privacy system" (don't know what it is called in the english version). After
installing the plugins package and selecting pgp-mime or pgp-inline the options
are disabled when I switch back to none.

Version-Release number of selected component (if applicable):
2.6.0-1

How reproducible:
don't know, but I guess always

Steps to Reproduce:
1. start sylpheed-claws
2. go to the account configuration and select privacy options

  
Actual results:

It is possible to select "encrypt every message" even when sylpheed-claws would
not do it because of missing plugin

Expected results:
Some information that a plugin is needed and disabled options to show that
further action is needed to make this work.
