I upgraded one of my PC's and all sorts of software started crashing, Evolution didn't even start before it crashed. So I did a clean install instead which seems to work fine so far. The upgrade worked better on the other machines, but there are still some unresolved issues, mostly segfaults.

Unofficial FreeBSD builds can be found at:

Hopefully, they will soon show up in the contrib directory of the official ftp also. //danne
