Help! Following what I thought was a routine upgrade of my Debian Jessie/Sid system, Trinity has broken. Completely. Many programs have disappeared from /opt/trinity/bin (most particularly kmail - I'm writing this on an old backup system).

I'm not sure there is much that can be done to avoid this; TDE does not yet have Jessie builds and it is quite possible that the dependencies changed enough to end up removing a large chunk of the TDE package set on upgrade.
Work to support Jessie is ongoing, just be patient. :-)
