Sorry for the delay, I was offline for a week and just catching up

You never run Evolution on this account between the last reboot and
restoring the old data? If not, you are right: --force-shutdown should
not do anything then.

Run 'evolution --force-shutdown' and restore the old data again. This
way should work, as long as the Contacts data isn't created by a very
anxious version of Evolution.

Yes, you should adjust the filters.xml file.

AFAIK the only directories with Evolution specific settings are in
~/evolution and ~/.gconf. You really can ignore the settings in the file
~/evolution/config.xmldb as this file isn't used since 1.3.x versions.

Dunno, but even after simply closing Evolution there are apps working
with some database files. Before editing them, you always should
--force-shutdown. Even reading may be an issue, as new contents are not
guaranteed to be written to disk before.

Yep, AFAIK.

These files are "safe" to be removed (in fact, I did it myself more than
once without real harm). But please note, that at least Labels are
stored in this files and that removing them will remove all your labels.

Changing the host name therefore will create a new directory and will
not have those stored labels. You can try renaming/copying this
directory -- I assume it will work, although I never tried it.


> P.S. Do you prefer if I send mail to the list only, without a copy to you?

I don't mind. But you sometimes will get my attention a little faster,
when Cc-ing me. ;)
