        Hi,
that's not possible to do with DConf/GSettings. GSettings relies on
schemas for the keys. When an application asks for a key which doesn't
exist then the application crashes. There is also a (strong) type
checking what the code expects to receive from the key and what type
the key is defined in the schema. Basically, neither users nor the code
can add any key, which doesn't have its corresponding record in the
schema (there are so called relocatable schemas, but even those are
defined in the schema).

This could be done in GConf times. It survived keys without schema with
no problem.

More likely is that the distribution has added a custom patch in the
evolution package. Eventually Iain did some (partial) build of more
recent Evolution on the machine into the system prefix, which brought
in the schema, but then runs older evolution, which doesn't know the
key.
