After some package update i found sysclean to mark /usr/lib/libz.so.5.0 as deletable because of no depends, which broke bogofilter in the flavor sqlite3.
To solve the problem for me i added WANTLIB z to *my* flavor. I dont know, of it is needed in the other flavors too. So maybe the better solution would be adding z to the generic WANTLIB.
