And also incompatible with the LGPL I assume. Else one could simply 
write an LGPL'd wrapper library and then use this in a GPL program. But 
isn't that exactly what Konqueror does by using kssl? If there is no 
licensing problem between Konqueror and OpenSSL then there can't be a 
problem with KMail (resp. the kssl based S/MIME plugin) since both use 
OpenSSL through kssl. Am I missing something?
