Bug#365348: Kmail: IMAP-SSL borkage

[Alver <alver@jesuschrist.be>]

According to the kdepim people, sasl *is* still used for imap-ssl in kmail; 
apparently libsasl2-modules should suffice.

Currently installed sasl-related packages:

ii  libauthen-sasl-cyrus-perl	0.13-server-1         
ii  libauthen-sasl-perl		2.10-1             
ii  libgsasl7				0.2.12-1                
ii  libsasl2					2.1.19.dfsg1-0.2         
ii  libsasl2-gssapi-mit		2.1.19.dfsg1-1     
ii  libsasl2-krb4-mit			2.1.19.dfsg1-1         
ii  libsasl2-modules			2.1.19.dfsg1-0.2      

Something must have gotten broken in the kioslaves <-> saslmodules link around 
the Xorg7 transition.
