Perhaps something broken with the Diversion-Thing?

Yes, see (some things come multiple times, see below):

But I found that (and remembered that this bit me):

Errors were encountered while processing:

Log ended: 2009-10-08  11:40:55

I removed libarchive-tar-perl and it's dependencies (mainly  
spamassassin) so I could continue the dist-upgrade and (re)installed  
spamassassin afterwards. Maybe here is the problem? Interrupted  
package installation? Or because of the install order (first perldoc,  
then perl)?
