That seems reasonable to me. Thanks for alle the explanations!

The best from an user perspective would be a message that the disk is
full and not to crash later (like Tomboy does).

Another related issue are blank or truncated messages in the message
view on diskfull. Usually I am bored by the dialogues asking for a
connection turning to offline mode but in this case I dialogue would
make a lot of sense to make it clear, that there is disk space problem
and no connection error.
