in kmail-1.9.1 on kde 3.5.2 i can't use crypto anymore, 'Configure->Security->Crypt backends' insists i should have Chiasmus, and i can't deselect that. 'Tools->Certificate Manager' also throws an error from Kleopatra: "The crypto plugin could not be initialized. Certificate Manager will terminate now."
I think it's similar to the following bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=136533
Is this still an issue with kde-3.5.6?
