Yes, I used your hint and refined it a little bit:

First, the old assets have to be removed:

   # rm -rf /var/cache/redmine/default/public/assets/*

then rebuild the assets, taking some wisdom from the redmine.postinst script:

   # su -s <REDMINE_CURRENT_USER> /bin/sh -c "cd /usr/share/redmine ;
REDMINE_INSTANCE=<INSTANCE> bundle exec rake assets:precompile
RAILS_ENV="production" RAILS_RELATIVE_URL_ROOT=/<SUB-URI>"

(the line breaks are horrible, please correct it in the README)
Using 'assets:clobber' instead of 'assets:precompile' fails because rake then
tries to remove the link '/var/lib/redmine/default/public/assets' owned by user
root.

In the UPGRADING document it says: "By default, Redmine automatically recompiles
assets in production mode when the application starts."
And indeed, doing

   # service unicorn stop
   # rm -rf /var/cache/redmine/default/public/assets/*
   # service unicorn start

the assets are rebuild correctly by redmine. Only difference is the ownership of
the files in /var/cache/redmine/default/public/assets/ which now belong to user
root.

Thanks for taking care.

Regards,
Jörg.
